    The link reaction is the second stage in aerobic respiration, it occurs in the mitochondrial matrix. It is aptly named the link reaction as it essentially links glycolysis and the Krebs cycle.

    At the start of the link reaction, pyruvate from glycolysis is decarboxylated to form acetate and a molecule of carbon dioxide. Acetate then combines with coenzyme A to produce acetyl CoA, at the same time a molecule of NAD is reduced to form reduced NAD. Acetyl CoA then plays an important part in the next stage of aerobic respiration when it combines with oxaloacteate to begin the Krebs cycle.

    The link reaction must occur twice for each molecule of glucose being respired (as glycolysis produces 2 molecules of pyruvate).
