Which enzyme of the Krebs cycle is uniquely located in the inner mitochondrial membrane rather than the matrix?
Show answer and explanation
Correct answer: Succinate dehydrogenase
Succinate dehydrogenase is membrane-bound and also acts as Complex II of the Electron Transport Chain. It catalyzes the oxidation of succinate to fumarate and the simultaneous reduction of FAD to FADH2.
