Vedclass · Answer

(A) In the Krebs cycle (also known as the Citric Acid Cycle),the conversion of succinyl $	ext{CoA}$ to succinic acid is catalyzed by the enzyme succinyl $	ext{CoA}$ synthetase.This reaction involves the coupling of the cleavage of the high-energy thioester bond of succinyl $	ext{CoA}$ with the phosphorylation of $	ext{GDP}$ (or $	ext{ADP}$) to form $	ext{GTP}$ (or $	ext{ATP}$).This process is known as substrate-level phosphorylation because the phosphate group is transferred directly from a substrate to $	ext{GDP}$/$	ext{ADP}$ without the involvement of the electron transport chain.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

Assertion: In Krebs cycle,there is a one step where substrate level phosphorylation occurs.
Reason: During the formation of succinyl $\text{CoA}$ to succinic acid,a molecule of $\text{GTP}$ is synthesized.
