The complex II of mitochondrial electron transport chain is also known as
Correct Answer :
Succinate dehydrogenase
Solution :
Complex II of the mitochondrial electron transport chain is the enzyme that catalyzes the oxidation of succinate to fumarate while simultaneously reducing ubiquinone to ubiquinol.
Because this enzyme resides both in the inner mitochondrial membrane (as part of the respiratory chain) and in the citric‑acid‑cycle matrix side (oxidizing succinate), it is commonly referred to by the name of its catalytic activity:
Succinate dehydrogenase.
Thus, the alternative name for Complex II is **Succinate dehydrogenase**.
