Pyruvate oxidation and
the citric acid cycle (krebs cycle, tricarboxylic acid cycle)
questions:
12. write the overall reaction for pyruvate oxidation (for one pyruvate):
-
pyruvate + __

15. per glucose, how many pyruvates (and then acetyl-coa molecules) are formed?
16. how many citric acid cycle's have to take place to break down the pyruvates from one glucose molecule?
