Energy Production of the TCA Cycle Flashcards
1
Q
How many electron pairs is generated by the oxidation of the acetyl group to 2 CO2 in the TCA Cycle? How are these electrons captured?
A
4; 3 in NADH and 1 in FADH2
2
Q
How many ATP does each turn of the TCA cycle produce?
A
10 ATP; 9 from NADH/FADH2 and 1 from GTP
3
Q
How many ATP, pyruvate, and NADH are produced in glycolysis?
A
2 ATP, 2 pyruvate, and 2 NADH
4
Q
What ultimately happens to the 2 pyruvate produced by glycolysis under aerobic conditions prior to the TCA Cycle?
A
They are converted by pyruvate dehydrogenase into 2 acetyl-CoA and 2 NADH.
5
Q
How many ATP does two turns of the TCA Cycle yield?
A
20
6
Q
How many ATP does 1 glucose produce under aerobic conditions?
A
32 ATP
7
Q
How many ATP does 1 glucose produce under anaerobic conditions?
A
2 ATP
