Question

First reaction in pentose phosphate pathway is

• A. Oxidation of glucose- 6 -phosphate
• B. Oxidation of 6-phosphogluconic acid
• C. Oxidation of ribose- 5 -phosphate
• D. Oxidation of fructose-5-phosphate

Answer 1

The correct option is A Oxidation of glucose- 6 -phosphate

The pentose phosphate pathway is a metabolic pathway which is carried out in most of the organisms. This pathway occurs parallel to glycolysis. This pathway produces pentoses from Glucose 6-phosphate. The first reaction is the oxidation of the Glucose 6-phosphate.

Thus, the correct answer is option A.
