Answer:
The key intermediate compound linking glycolysis to the Krebs cycle is Acetyl CoA.
During glycolysis, pyruvic acid is formed as an end product which is further decarboxylated in an oxidation reaction to form Acetyl CoA. This takes place through a multienzyme complex and cofactors to form carbon dioxide and NADH in addition.
The Acetyl CIA then passes over to the Krebs cycle to proceed with the rest of the steps. Therefore, it is said to be the link between glycolysis and the Krebs cycle.
