In the Krebs cycle, the FAD electron transport system operates during the conversion of:
Correct answer: C. Succinic acid to fumaric acid
- A. Succinyl CoA to succinic acid.
- B. α - ketoglutarate to succinyl CoA
- C. Succinic acid to fumaric acid
- D. Fumaric acid to malic acid
Explanation
The FAD electron transport system operates during the conversion of succinate to fumarate in the Krebs cycle.The Krebs cycle, also known as the citric acid cycle or the tricarboxylic acid (TCA) cycle, is a series of chemical reactions that are used by all aerobic organisms to generate energy. The Krebs cycle takes place in the mitochondria of cells.

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.
