The precursor of fumarate during Krebs cycle requires _ for fumarate synthesis:
Correct answer: C. Succinate dehydrogenase
- A. Amino acid aspartate
- B. Fumarate dehydrogenase
- C. Succinate dehydrogenase
- D. FAD+ oxidase
Explanation
Succinate dehydrogenase is the enzyme that catalyzes the conversion of succinate to fumarate in the Krebs cycle, making it the correct choice for fumarate synthesis.

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.
