Question

I need to correct answer for #16.

a) 32 b) 30 d) 35 e) None of the above NAD FADH 16. The reduction of one NADH and one FADH2 molecule from citric acid cycle leads to the formation of these ATP molecules in oxidative phosphorylation: ) 2.5 d) 8 e) You can't fool me. Both are already reduced. 17. The citric acid cycle takes place in: a) Cyoplasm b) Matrix of mitochondria c) nner membrane space of mitochondria Inner membrane of mitochondira Outer membrane of mitochondira e) 18. Which of the following must be regenerated for glycolysis to proceed?

Explanation / Answer

The reduction of one NADH and one FADH2 molecule from citric acid cycle leads to the formation of 4 ATP molecules in oxidative phosphorylation.

Because for every  NADH and FADH2 molecule from citric acid cycle yields 2.5 ATP/NADH and 1.5 ATP/FADH2 molecules respectively in oxidative phosphorylation (electron transport chain)

They synthesise ATP molecules is by oxidation of NADH (loss of elcetrons) and FADH2 is also transfer its electrons to coenzyme Q.

so for 1 NADH and 1 FADH2 produced in krebs cycle or TCA cycle yields 2.5+1.5 = 4 ATP molecules in oxidative phosphorylation of electron transport chain (ETC).
