Question

How do we know that oxidation reactions have occurred in the Citric Acid Cycle?

Answer 1

do you have multiple choice?

Answer 2

After entering the mitochondria, pyruvate dehydrogenase catalyzes pyruvate oxidation to Acetyl-S-Coenzyme A (Ac-S-CoA). Then the Krebs cycle completely oxidizes the Ac-S- CoA. These mitochondrial redox reactions generate CO2 and lot of reduced electron carriers (NADH, FADH2).

Answer 3

here are the choices:
A: Water is produced.

B: NADH and FADH2 are formed.

C: Coenzyme A binds to an acetyl group.

D: Oxygen is used.

Answer 4

yes I have multiple choice @jkmiec26

Answer 5

not A or B so its C or D which one do u think?

Answer 6

okay I knew it wasn't A, but I was trying to pick from the other choices.

Answer 7

its between C and D

Answer 8

D doesn't make much sense because oxygen can be used at other times than this situation, so it must be C.
