Just know what is oxidized, what is reduced, reactants, products, number of ATP, NADH, FADH, etc. are made in glycolysis up to the end of the krebs cycle. Understand the overall concept, you don't really need to know all the nuts and bolts. Don't waste time memorizing all the intermediates and enzymes involved.
You need to memorize every enzyme, every intermediate, and the sterochemistry of each carbon in every reactant, intermediate, and product
Just kidding. Just know number of carbons for everything, when ATP, GTP, NADH, and FADH2 are made, and how many of all those thins are made per glucose.
Sorry to bump this but do we have to know the names of all the intermediate steps (i had to for university bch course). Like bisphosphate, ... or just pyruvate, glucose, acetylcoa. but not all the steps in krebs. I'm just asking to make sure, it won't be any trouble to do so b/c i did earlier this year.
