Question

Oxidative phosphorylation of cytoplasmic $NADH\left(H^{+}\right)$ takes place in

• A. Cytosol
• B. E.R.
• C. Mitochondria
• D. Golgi bodies

Answer 1

The correct option is C Mitochondria

A large amount of NADH produced during glycolysis and Krebs cycle undergoes oxidation with phosphorylation of ADP to form ATP which is supported by mitochondrial electron transport assembly and ATP synthase which are integral protein complexes of the inner mitochondrial membrane. The electron transport assembly is comprised of a series of protein complexes that catalyze sequential oxidation-reduction reactions.

Thus, the correct answer is option C.
