Vedclass · Answer

(A) In the $Krebs$ cycle (also known as the Citric Acid Cycle),one molecule of acetyl-$CoA$ enters the cycle. During the conversion of succinyl-$CoA$ to succinate,one molecule of $GTP$ (guanosine triphosphate) is produced via substrate-level phosphorylation. This $GTP$ is energetically equivalent to one $ATP$ molecule. Therefore,$1$ $ATP$ (or $GTP$) is produced directly per acetyl-$CoA$ molecule in the $Krebs$ cycle.

How many $ATP$ molecules are produced directly in one $Krebs$ cycle per acetyl-$CoA$ molecule?
