Chemical forumlas in Kreb's Cycle and Glycolysis...

[passion2K7]

Hey guys,

I am currently studying metabolism stuff, and have a quick question. I wanted to know if I need to know the chemical forumlas in Glycolysis and Kreb's cycle for the MCAT.

no
just which steps are aerobic / anaerobic. recognize pyruvate as 1/2 glucose too.

Thx for the quick reply.

When you say which steps are anaerobic/aerobic, you mean glycolysis+pyruvate oxidation+cytric acid cycle+respiratory chain for aerobic vs. glycolysis+fermentation for anaerobic?

For glycolysis, I know that it changes glucose (6c molecule) to two pyruvate (3c molecules), NAD+ into NADH +H, and 2 ADP+ PI -> 2 ATP's. Am I responsible for 10 steps within glycolysis. They seem to contain too much detail, and all I remember now is just that the first half steps are endergonic, while the rest are exergenic (enever-harvesting reactions to produce ATP's).

For the Kreb's cycle, am I responsible for each step (such as taking NAD+ -> NADH + H & CO2 when going from Isocitrate to a-Ketoglutarate... etc)?

Again, thx for the replies! =)

For class you might need to know them (I did) but I think it is beyond the scope of the MCAT.

They won't ask a stand alone about the 6th step of the krebs and the enzyme used.

yes, you heard me right

and you should know that NADH is the 'charged' form... reduced

ps, brett, have you taken the mcat yet I see your posts everywhere, what stage in the application process are you?

I'm prepping now yet I have obtained a wealth of info from various places.

in o-chem section of mine had to know stucture (fischer projections) of various sugars (like fructose, glucose, galactose) at least biochem was good for something.........

Anything else from biochem?
