In the following question, a statement of assertion is followed by a statement of reason. Mark the correct choice as
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.
In the following question, a statement of assertion is followed by a statement of reason. Mark the correct choice as
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.
The correct option is B If both assertion and reason are true but reason is not the correct explanation of assertion.
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. This step of glycolysis is the enzymatic transfer of a phosphate group from 1,3-bisphosphoglycerate to ADP by phosphoglycerate kinase, forming ATP and 3-phosphoglycerate. The direct synthesis of ATP from metabolites is called substrate-level phosphorylation. This is a break-even point of glycolysis where 2ATPs have been consumed and two new ATP molecules have been produced.
