Which is the connecting link between glycolysis and Krebs cycle?

A)                  Acetyl Co - A                    

B)                  Pyruvic acid

C)                  Both (a) and (b)                              

D)                  None of the above

Correct Answer: A

Solution :

                 Substrate entrants of Krebs cycle is acetyl Co A which is also considered as connecting link between glycolysis and Krebs cycle. Pyruvic acid is the product of breakdown of glucose molecule during glycolysis. It takes part in different types of fermentation reaction in anaerobic conditions and forms acceptor molecules of Krebs cycle under aerobic condition.
