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.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
Step-by-step 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.
