Question

Which one among the following is oxidative step of glycolysis?

• A. Phosphoglycerate $\to$ phosphoenol pyruvate
• B. Glyceraldehyde $3-$ phosphate $\to$ $1,3-$bis Phosphoglycerate
• C. Phospho enol pyruvate $\to$ pyruvate
• D. Fructose $1,6-$ bis phosphate $\to$ Triose phosphate

Answer 1

The correct option is B Glyceraldehyde $3-$ phosphate $\to$ $1,3-$bis Phosphoglycerate

A. Phosphoglycerate by hydrolysis and enolase enzyme is converted to phosphoenol pyruvate.

B. Glyceraldehyde-3-phosphate is oxidized and with inorganic phosphate converted to 1,3-bisphosphoglycerate.

C. Phosphoenol pyruvate by pyruvate kinase gets converted into pyruvic acid and ATP is released.

D. Fructose 1,6-bisphosphate by the action of aldolase converts into triose phosphate.

So, the correct answer is 'Glyceraldehyde 3− phosphate → 1,3−bis Phosphoglycerate'.
