Vedclass · Answer

(C) Assertion $(A)$: The $TCA$ cycle (Tricarboxylic Acid cycle) or Krebs cycle begins with the condensation of the acetyl group $(2C)$ with oxaloacetic acid ($OAA$,$4C$) and water to form citric acid $(6C)$. This reaction is catalyzed by the enzyme citrate synthase. Thus,$A$ is correct.Reason $(R)$: The Krebs cycle takes place in the mitochondrial matrix of eukaryotic cells,not in the cytoplasm. Glycolysis is the process that occurs in the cytoplasm. Thus,$R$ is incorrect.Therefore,the correct option is $C$.

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

$A -$ The $TCA$ cycle starts with the condensation of Acetyl group with $OAA$ and water to yield citric acid.
$R -$ Kreb's cycle occurs in the cytoplasm of the cell.
