The connecting link between glycolysis and Krebs cycle is

A

Pyruvic acid

B

Acetyl Co-A

C

Oxaloacetic acid

D

Phosphoenol Pyruvate

Text Solution

Verified by Experts

The correct Answer is:
B

After glycolysis, pyruvic acid enters the matrix of mitochondria and undergoes acetylation by oxidative decarboxylation to form 2-carbon compound acetyl Co A. This step is also called gateway step of link reaction or transition reaction. This acetyl Co-A or activated acetic acid acts as connecting link between glycolysis, Krebs cycle and oxidation of fats.
