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

Options

A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false
D. If both the assertion and reason are false

Answer

B

Explanation

In glycolysis the direct synthesis of ATP occur from metabolites called substrate level phosphorylation.
When 1, 3 bisphosphoglyceric acid is converted to 3 phosphoglyceric acid by the activity of enzyme phosphoglycerate transphosphorylane. During this reaction ADP is converted to ATP .
