In one turn, the Krebs's cycle produces one molecule of ATP, one molecule of FADH2 and _ molecules of NADH.
Correct answer: C. 3
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
In one turn of the Krebs cycle, one molecule of ATP, one molecule of FADH2, and three molecules of NADH are produced. The ATP is generated through substrate-level phosphorylation, while FADH2 and NADH carry high-energy electrons that will be used in the electron transport chain to produce additional ATP during oxidative

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
