Solution

The correct option is D A- $1$ , B- $4$ , C- $2$ , D- $5$
Pyruvate oxidation duringKrebs cycle converts pyruvate, a three-carbon molecule into acetyl CoA.
The isocitric acid is converted to oxalosuccinic acid.
Alpha-Ketoglutaric acid is converted into succinyl-CoA and produces NADH directly providing electrons for the respiratory chain.
Succinate (succinic acid) is oxidized to fumarate (fumaric acid) by succinate dehydrogenase during the Krebs cycle.
So the correct answer is option D.
