Vedclass · Answer

(A) The $TCA$ cycle (Tricarboxylic Acid cycle) or Krebs cycle involves a series of enzymatic reactions where one molecule of Acetyl $CoA$ is oxidized.During one turn of the $TCA$ cycle,the following steps produce reduced coenzymes:$1$. Isocitrate to $\alpha$-Ketoglutarate: $1 NADH + H^+$ is produced.$2$. $\alpha$-Ketoglutarate to Succinyl-$CoA$: $1 NADH + H^+$ is produced.$3$. Succinate to Fumarate: $1 FADH_2$ is produced.$4$. Malate to Oxaloacetate: $1 NADH + H^+$ is produced.Thus,for one molecule of Acetyl $CoA$,the total yield is $3 NADH + H^+$ and $1 FADH_2$.

Column $I$	Column $II$
$i.$ Isocitrate dehydrogenase	$a.$ Citrate $\rightarrow$ Cis-aconitate
$ii.$ Fumarase	$b.$ Succinate $\rightarrow$ Fumarate
$iii.$ Aconitase	$c.$ Fumarate $\rightarrow$ Malate
$iv.$ Succinate dehydrogenase	$d.$ Isocitrate $\rightarrow$ Oxalosuccinic acid

In $TCA$ cycle,how many reduced coenzymes are produced from one Acetyl $CoA$?
