Both NADH and FADH2 are formed during:

Correct answer: C. Kerbs cycle

  • A. Glycolysis
  • B. The electron transport system
  • C. Kerbs cycle
  • D. Fermentation

Explanation

The cyclic reactions of Krebs cylce produce both NADH and FADH2, while in glycolysis, only NADH is produced. During electron transport chain, these NADH and FADH2 molecules are oxidized to produce ATP molecules

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.
