Function of succinate dehydrogenase is aided by:
Correct answer: B. FAD
- A. NAD
- B. FAD
- C. Metal ion
- D. Vitamin
Explanation
Succinate dehydrogenase is an integral enzyme in the citric acid cycle and the electron transport chain. It catalyzes the oxidation of succinate to fumarate, using FAD as a cofactor. FAD accepts electrons, forming FADH , which then donates electrons to the electron transport chain, contributing to ATP synthesis through oxidative phosphorylation. NAD, metal ions, and vitamins do not serve as direct cofactors for this enzyme's specific action within these pathways.
