Solution
The correct option is D Succinate dehydrogenase
In aerobic respiration, succinate dehydrogenase is used both in Krebs cycle and electron transport chain (ETC).
In Krebs cycle, it catalyses the conversion of succinate to fumarate.
In the electron transport chain, it is the main constituent of complex II. It acts as an electron receiver and accepts electrons from FADH2 and transfers the electrons to complex III.
