FADH2 is produced in_:
Correct answer: C. Kreb's cycle
- A. Glycolysis
- B. The oxidation of pyruvates
- C. Kreb's cycle
- D. All of these
Explanation
FADH2 (flavin adenine dinucleotide) is produced during cellular respiration, specifically in the citric acid cycle (also known as the Krebs cycle). The citric acid cycle is a series of chemical reactions that take place in the mitochondrial matrix, and it plays a central role in the breakdown of acetyl-CoA (a two-carbon compound derived from the breakdown of glucose) and the production of energy-rich 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.
