In cellular respiration, the molecules of nicotinamide adenine dinucleotide (NADH) and Flavin adenine dinucleotide (FADH) are produced during:
Correct answer: B. Krebs cycle
- A. Glycolysis
- B. Krebs cycle
- C. Pyruvate oxidation
- D. Electron transport chain
Explanation
The correct answer is the Krebs cycle.During cellular respiration, NADH and FADH2 are primarily produced in the Krebs cycle.

About Cellular Respiration
Cellular respiration releases energy from glucose through glycolysis, the link reaction, the Krebs cycle and the electron transport chain, producing ATP. The pathway differs in oxygen availability: aerobic respiration uses oxygen and yields more ATP, while anaerobic respiration produces much less ATP and forms lactic acid in muscles or ethanol and carbon dioxide in yeast.
