Link enzyme in cellular respiration which catalyzes the substrate produced during glycolysis, and funnels it into the Kreb's cycle is ______.
Pyruvic acid synthesized in glycolysis must enter inside the mitochondria, where oxidative decarboxylation occurs in the presence of NAD+ and coenzyme-A. This results in the formation of acetyl CoA which can enter the Kreb's cycle. This reaction is catalyzed by pyruvate dehydrogenase.
