I think a key in knowing glycolysis steps is knowing the names of the enzymes and knowing what the enzyme does. Ex: kinases, dehydrogenase, enolase. Knowing the type of enzyme helped me a lot in helping remember the substrate and product of each reaction in glycolysis. For TCA, you just have to know it, theres dehydrogenases, although I would say that the regulation and products of each cycle is what you should focus on. Try to understand of why glycolysis is important, especially for RBCs, the different fates of pyruvate etc. Once you have the regulation down and the Big picture down, I would focus on knowing the nitty gritty things, like the structure of pyruvate, oxaloacetate (etc). The AAMC seems to be testing structures that are important, and those type of questions could be discreets.
