Succinate is oxidized and forms:
Correct answer: C. FADH2
- A. FAD
- B. FADH
- C. FADH2
- D. NADH2
Explanation
Succinate is oxidized to fumarate in the citric acid cycle, and during this process, FAD is reduced to form FADH2. FADH2, along with NADH, plays a crucial role in the electron transport chain to produce ATP during oxidative phosphorylation. The overall reaction is: Succinate+FAD→Fumarate+FADH2

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.
