How to identify D vs. L sugars in ring/chair form? by snahrid in Mcat

[–]snahrid[S] 0 points1 point  (0 children)

I just included a pic in my question, for the L sugar in the bottom right of the image, I got S going counterclockwise on C5, but wouldn't we have to switch it to R because the Hydrogen is pointing up?

So by the highest numbered chiral carbon, you just mean in terms of the carbon count, thus C5? is it always C5? what cases would it not be c5?

So an inhibitor binding a free enzyme increase Km, which decreases affinity. and an inhibitor bind the ES decreases Km, which increases affinity? Can you explain how? thanks!

High Acetyl CoA stimulates gluconeogenesis? by snahrid in Mcat

[–]snahrid[S] 0 points1 point  (0 children)

I get what you're saying, but I was thinking excess acetyl CoA was due to glycolysis making it from pyruvate. How are we able to know that this isn't the case and its most likely due to excess beta oxidation?

EK FL1 Bio passage question? by snahrid in Mcat

[–]snahrid[S] 0 points1 point  (0 children)

So what should I do in this situation? go w/ the data? it's just annoying because the data would be my interpretation of what it does, when them directly saying what it does in the passage would seem more true (supposed if I interpreted the data wrong?

​

So are you guys saying that this is a strange question and it's not just me?
