Question

Which of the following pathway is primarily supported by glycerol-3-phosphate shuttle?

• A. Glycolysis
• B. Oxidative phosphorylation
• C. Fatty acid synthesis
• D. None of the above

Answer 1

The correct option is B Oxidative phosphorylation

Glycerol phosphate shuttle is a mechanism that regenerates NAD${}^{+}$ from NADH. In this, glycerol-3-phosphate dehydrogenase enzyme converts dihydroxyacetone phosphate to glycerol 3-phosphate by oxidizing NADH to NAD${}^{+}$. Hence, it supports oxidative phosphorylation by contributing NADH to the oxidative phosphorylation.

Thus, the correct answer is 'Oxidative phosphorylation.'
