Which one of the following reactions, ADP/ATP is not involved in phosphorylation?

Options

  1. AGlucose Glucose 6 phosphate
  2. BFructose 6 phosphate Fructose 1, 6 diphosphate
  3. CGlyceraldehyde 3 phosphate 1,3 biphosphoglycerate
  4. D1,3 bisphosphoglycerate 3, phosphoglycerate

Correct answer

C. Glyceraldehyde 3 phosphate 1,3 biphosphoglycerate

Step-by-step solution

In glycolysis, the conversion of glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate is catalyzed by the enzyme glyceraldehyde 3-phosphate dehydrogenase. During this step, inorganic phosphate ( P_i ) is added to the molecule, and NAD^+ is reduced to NADH + H^+ . ATP or ADP is not involved in this specific phosphorylation reaction. In contrast, the phosphorylation of glucose and fructose 6-phosphate utilizes ATP as the phosphate donor. The conversion of 1,3-bisphosphoglycerate to 3-phosphoglycerate involves the tr
