Answer:
Correct Answer: B
Solution:
One of the two phosphates of diphosphoglycerate is linked by high energy bond.
It can synthesize ATP and form 3-phosphoglycerate.
The enzyme is phosphoglycerate kinase.
The direct synthesis of ATP from metabolites is called substrate level phosphorylation.
During formation of phosphoenol pyruvate the phosphate radical pick up energy.
It helps in the production of ATP by substrate level phosphorylation.
