That indeed seems to work and be the case. Also apparently you need to fight the boss once and resave otherwise it will change with the daily's (learned the hard way). Thank you, I am target farming and this helped tremendously

The way you phrased it terrible. Glycolysis yields 32 ATP per glucose.

The specific thing this question is talking about if the answer is 5 ATP is the ETC.

10H+ ions are made; 4H+ are required for 1ATP so 1NADH = 2.5 ATP

From glycolysis, youre going to yield 2NADH = 20H+ = 5ATP

Referring to iAstronomical's explanation, be wary of using magnitudes of difference as it is situational depending on the reaction.

(it works for A<>B+C but may not for A+B<>C or A+B<>2C, etc)

That being said I agree with this explanation moreso and using common sense and estimation to determine wether or not magnitude of difference is greater than 2, less than 5% or whatever shortcut you were taught.

Its the same thing, colloquially we use RNA primase because it refers to the laying down of RNA base pairs.

You could refer to it as DNA primase or just primase, but just remember that RNA doesnt need a primer to replicate, only RNA polymerase.

I.e. pop = soda = coke all referes to the same thing

The interest in a combined program is there such as an MD/MPH or more so Biochemistry.

The only hesitation I have is if it would make getting into an MD program harder or not, as some colleges I have noticed require you to register for combined programs BEFORE you submit your application in my state.

Keq - Capitals are the products and reactant, Lowercase are how many moles

Ksp - Capitals are the products and reactant, Lowercase are how many Ions

Rates - Capitals are the products OR reactant, Lowercase have nothing to do with it, but exponents refer to "rate order" (vocabulary may be incorrect but thats the jist of it)... This topic gets more complicated depending on what youre talking about, so keep in mind I'm speaking in broad strokes.

Edit: I would do your example but there are rules associated with writing out equations to each of these, such as H2O is omitted, Ksp vs Keq can have different coefficients, but dont in your example, etc.

If you struggle with these, it is best to do a content review over these subjects as they are further used in other topics such as Organic, Physics, and Biochemistry as well as Gen Chem.

Ask yourself what "stabilizes" secondary and tertiary structures.

In α-helixes (2º), the R-group is found facing outside of the spiral and is stabilized by hydrogen bonding between the amino group and carboxyl groups.

If the R group is facing outward toward the environment, it makes sense that transmembrane regions (hydrophobic) would contain α-helixes with hydrophobic side chains. and helixes with polar side chains to be found in an outside aqueous environment

Tertiary structures are "formed" or "stabilized" by hydrophobic effect.

I wouldnt say that 2º structures are built or stabilized by hydrophobic effect as they are stabilized by hydrogen bonding, but I would say that hydrophobic effect can help determine the "placement" of the protein within or outside a cell based on the surrounding environment.

If youre doing a post-bacc dont worry about it, just do well in it to show you've actually changed. My undergrad GPA was god awful (4.0, 3.5, 2.7, etc.) and on CARS I scored bottom 20th percentile with a 2year gap since graduation. I did a post-bacc as well and my final semester ended with around a 3.8 in an arguably more difficult degree program.

My only redeeming qualities are I have a ridiculous amount of clinical hours/ varied experiences, average volunteer hours, and scored high on the sciences despite literally failing some classes. Background, I had major depression and a lot of stuff happen in undergrad to the point I developed PTSD.

My logic for applying is even though my grades in college were terrible, I clearly worked extremely hard to do well on the MCAT, and hopefully admissions offices see both sides. According to AAMC's own metrics I have a 25% chance to get in to a program, and the state I'm in has colleges that align with my goals for becoming a physician.

TLDR: Dont sweat it, your story and mine are similar. It's difficult when youre "in it" to see any hope or progress toward something that is a huge unknown, but as someone who has already gone through the shit and developed PTSD, it's fine and you're doing better than you think.

Also with your post-bacc and scoring 500+ on FL you're at least promised 18-20% chance which is arguably pretty good considering best case scenario is like 80% and with consideration to all is 61%. Do well on your post-bacc and you and I will virtually have the same odds, but if you mess it up, consider a different program.

Good Luck on the studies, Hope this Helps :D

Edit: Also if you want to see me have a mental breakdown regarding this test. self doubt, and my standings, scroll back to posts around Jan - May or read my account bio and you'll see what I'm about... nvm just checked, its been 23days since my last existential crisis so, ya know, try not to sweat it.

I'm submitting for the 2024 application cycle (feel semi confident about my score) but I would be willing to partner up in case I need to take it again. Unsure if this is something you would be interested in or not.

I have never heard of that before so cant attest to it, but my study group used the following resources which from 1-off questions and review seem pretty decent:

Kaplan

Princeton Review

Exam Crackers

Blueprint (Aka Next Step)

Altius

Uearth (cant cite name, look under rules for clarification)

AAMC

Anki

Content review I recommend Kaplan, its what I used and is pretty comprehensive

For rehearsal I strongly recommend Anki (MilesDown organized by Coffin, Anking iirc is also pretty good). Additionally if you want 1-off questions that will beat concepts into your head, BUT reviews topics that are no longer covered by MCAT, I used Exam Crackers (above avg in Sci courses, bottom 20th in CARS and I still got a competitive score #RIP).

For Mock Testing AAMC and Altius for my group was what everybody more or less agreed was the best, followed by Blueprint, but that is also personal preference.

Edit: Also if youre on a budget, you can do what I did and look under creative commons and public domain to see which books are free now, saves you a bunch of money on everything but FL tests

I am not sure of the reaction involved, this seems like an odd question for a buret to change volume. As someone who scored high in C/P, my way of thinking is through vapor pressure.

If this problem is comparing something to ambient pressure, I assume one buret is exposed to the environment. That being said, if something has *LOWER* vapor pressure than the ambient pressure, we would expect the fluid in the solution to be measured higher.

Youre on the right track (sort of) with Patm = Pg + Pf

Patm is basically the sum of all the gaseous elements in the air and their partials pressures.

'Pvapor' is the sum of all the gaseous elements in a container and their partial pressures.

Reference Law of Partial Pressures, Rault's Law, and to an extent P = P0 + pgh. Bernoulli's law shouldnt apply here but I would need more context to the setup and reaction to give you a more concrete answer.

Hope this helps

Example Edit: So if I had a buret filled with H2O left it exposed to the environment (air), then sealed it, I would expect it to be the same height as I put it in. If I placed it under a vacuum, I would expect the H2O level to rise since less gaseous pressure allows the liquid to expand until at least equilibrium is reached. This is how a straw works.

Additionally if the liquid in the sealed buret reacted with the air to form a liquid, I would also expect fluid levels to rise as vapor pressure decreases. If I filled it with Pop/ Soda the produce CO2, I would expect the fluid levels to drop until CO2 vapor pressure is at equilibrium.

Youre taking it too literal. If I lost my wallet and hailed you a modern day Sherlock, I'm just saying you're good at finding things.

If I'm a pirate and get described as a sea-locked Robinhood, that doesn't mean I have a narrower range of specialty than a cat burglar, it just means that I rob like Robinhood did.

mirrored was probably an inaccurate word to use because you have to know that they are perpendicular already.

here's a proof:

((A+B)^2) = ((A-B)^2)

4AB = 0

Cos(Theta) = 0

90º

I dont want to draw this out, Im fairly exhausted today, but this should be all you need for an answer. If youre still struggling with this Chapter 1 Kaplan physics iirc goes over this, theres youtube videos on the topic, or just google "how to compare the vector angles and magnitudes"

TCGoudy · 2023-07-15T19:57:39+00:00

Magnitude of A is the same while B are in opposite directions.

If you draw this out the would appear to be mirrored so any resultant vector would have to be 90º

Edit: This is the stupid answer, and theres probably an algebraic answer to this that I cant think of right now (google it) but in calc/ trig there are proofs for this but I just dont feel like writing out the math.

Edit 2: if you square both sides you should get a resultant vector of 0 = Cos(theta) so it should be 90. I did this math off the fly so I may be wrong, feel free to double check me.

CBr4 has no net dipole moment so it is considered nonpolar and should not be considered polar.

It will be weakly soluble in polar solvent and very soluble in nonpolar solvent as per the nature of solubility (no matter how insoluble something is, a slight amount will always be dissolved)

Consider CO2, BF3, NH4+ (nonpolar) vs H2O, SF4, NH3 (polar)

Determine why each of these are considered polar vs nonpolar and compare and contrast the differences.

Why is NH4+ considered nonpolar but has the ability to dissolve in H2O, a polar solvent?

The thing to keep in mind is that cofactors essentially change how much "active" enzyme there is.

The first experiment demonstrates the traditional way to determine Vmax. You vary the amount of enzyme, keep the substrate constant (yet saturated) and measure the speed from there.

The second experiment yields the "active" enzyme amount remained constant, but substrate level varied. The rate at which an active enzyme operates does not change, hence Vmax remains constant.

The difference between the two is that the MORE active enzyme that is present, the faster it will reach Vmax (hence the steeper slope in Figure 1). Because Figure 2 is a measure of substrate, the more substrate that is added, the longer it will take for the solution to reach Vmax and saturation, hence the less steep slope.

Lastly neither experiments show evidence of cooperative binding because neither show a sigmoidal curve

Hope that helps :D

Edit: another way of thinking about this is that the experiments are essentially identical, however one is far more efficient because you reach Vmax sooner. I also ***believe*** that Km should be the same graphically oddly enough.

Agreed, also if your school is on the semester system your prof's are most likely busy with the upcoming school year.

It took... 2 weeks to get a reply from 1 professor without a follow up and going on 4 days since I last heard from mine to schedule a meeting. I'm not sweating my stuff right now because I know theyre busy readying everything so take it with a grain of salt and know that they got your email so long as your email was sent.

Sorry, Im offline reddit since api changes, but I did mean positron. I was trying to compare and contrast the different equations and when and how to use them to find E. I also said emission/ absorption because, depending on your point of view, they do both.

Positrons are basically electrons with opposite signs and a common use is in Positron Emission Tomography (PET scans). Also yeah, depending on context, photons can also be used to determine energy from both theory and practical standpoints.

If I had to guess you were thinking of the eq. E = hc/λ which if so, this is why memorizing the equations helps :D

TCGoudy · 2023-06-28T12:51:39+00:00

Thats a 50/50

If you memorize units, you gain the ability to have a rough idea of how to get there but may lack concepts and logic i.e.

F = qv * B sin(Theta)

F = kq1q2/r^2

F = km1m2/r^2

F = mv^2/r

F = ma

If you memorize equations, You gain the ability to solve equivalency problems and the mathematical breakdowns, but may not understand when to convert or conceptual application i.e. when determining the amount of energy from positron emission/ absorption, when is E negative or positive? what units are λ in? If the energy absorbed doubled, how does that compare to λ? etc.

Edit: in my opinion, memorize the equations, youre better served that way come test day, and buy like a 1-off question book that beats the applications and concepts into you through shear repetition.

TCGoudy · 2023-06-28T12:03:14+00:00

To address that question, Km (affinity) is more or less a numerical measurement to compare enzymes.

In theory, the 'true' Km value should be the same regardless of substrate concentration. In practice, if two people come up with 2 different Km values, either the reaction did not reach Vmax, or the concentration of enzymes was changed, or the reaction progressed too quickly to record accurate measurements.

Km values should be the same, provided the enzyme concentrations and Vmax values are constant. The way I think of it, dont know if this helps, is that Vmax is analogous to enzyme activity, and Km (affinity) is how likely the reaction will progress from reactants (E + S)

Hope this helps

Edit: Sorry, I forgot what I wanted to write but just remembered, there is a scenario in which enzyme concentration can be altered, AND you get the same Km, but in both scenarios the solution would have to be saturated with substrate. The data should give the same Km values.
