Acetyl $CoA$ combines with pyruvic acid to form citric acid.

Vedclass · Answer

(D) The Krebs cycle (or Citric Acid Cycle) begins with the condensation of Acetyl $CoA$ $(2C)$ with Oxaloacetic acid $(4C)$ to form Citric acid $(6C)$.Option $D$ states that Acetyl $CoA$ combines with pyruvic acid,which is incorrect.In the cycle,$NAD^+$ is reduced to $NADH + H^+$ at three steps (Isocitrate to $\alpha$-ketoglutarate,$\alpha$-ketoglutarate to succinyl $CoA$,and Malate to Oxaloacetate).$FAD^+$ is reduced to $FADH_2$ at one step (Succinate to Fumarate).Substrate-level phosphorylation occurs during the conversion of succinyl $CoA$ to succinic acid,producing $GTP$ (or $ATP$).

Column-$I$	Column-$II$
$(a)$ $4$ $C$ compound	$(1)$ Acetyl $CoA$
$(b)$ $2$ $C$ compound	$(2)$ Pyruvate
$(c)$ $5$ $C$ compound	$(3)$ Citric acid
$(d)$ $3$ $C$ compound	$(4)$ $\alpha$-Ketoglutaric acid
	$(5)$ Malic acid
