Assertion: Substrate level phosphorylation is present in glycolysis.
Reason: Substrate level phosphorylation causes synthesis of ATP.

Answer

B

Explanation

One of the two phosphates of diphosphoglycerate is linked by high energy bond. It can snthesis ATP and form 3-phosphoglycerate. The enzyme is phosphoglycerate kinase. The direct synthesis of ATP from methabolites is called substrate level phosphorylation. During formation of phosphoenol pyruvate the phosphate radiacal pick up energy. it helps in the production of ATP by substrate level phosphorylation.
