Assertion : Conversion of 1,3 biphosphoglycerate (BPGA) to 3-phospho-glyceric acid (PGA) is an energy yielding step.
Reason : This energy is trapped in the form of ATP.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Solution
One of the two phosphates of 1,3 biphosphoglycerate (BPGA) is linked by high energy bond. It can synthesise ATP and form 3-phosphoglycerate by phosphoglycerate kinase enzyme. The direct synthesis of ATP from metabolites is called substrate level phosphorylation.
