Question

Common enzyme in glycolysis and pentose phosphate pathway is

• A. Hexokinase
• B. Aconitase
• C. Fumarase
• D. Dehydrogenase

Answer 1

The correct option is D Dehydrogenase

Dehydrogenase is the common enzyme which is involved in the glycolysis and pentose phosphate pathway. The enzyme carries out the dehydrogenation of the Glucose-6-phosphate at the first carbon. There is the production of NADPH in this reaction which is the prime product in the pentose phosphate pathway. The NADH${}_2$ is then used for the production of ATP through oxidative phosphorylation.

Thus, the correct answer is option D.
