Question

Reduced coenzyme NADPH $\left(H^{+}\right)$ is produced in respiration during

• A. Glycolysis
• B. PPP
• C. Krebs cycle
• D. Terminal oxidation.

Answer 1

Answer: (B)

PPP

PPP or pentose phosphate pathway is an important pathway that takes place in the cytoplasm.

It is an alternative path for the Krebs cycle and is the only pathway that forms reduced NADH. The enzyme transhydrogenase, that transfers the hydrogen of NADPH to NAD and forms NADH.

So, the correct option is 'PPP'
