Vedclass · Answer

(B) The link reaction,also known as the transition reaction,connects glycolysis to the Krebs cycle.During this process,pyruvic acid produced in the cytoplasm during glycolysis enters the mitochondrial matrix.Here,it undergoes oxidative decarboxylation in the presence of the enzyme complex $Pyruvate 	ext{ } Dehydrogenase$,$NAD^+$,and $Coenzyme-A$.The reaction is represented as: $Pyruvic 	ext{ } acid + NAD^+ + CoA \xrightarrow{Pyruvate 	ext{ } Dehydrogenase} Acetyl 	ext{ } CoA + CO_2 + NADH + H^+$.Therefore,$Pyruvate 	ext{ } Dehydrogenase$ is known as the link enzyme.
