Correct option (a) acetyl Co-A
Explanation:
During glycolysis 1 molecule of glucose is converted to 2 molecules of pyruvic acid in the cytoplasm. These two molecules of pyruvic acid is then converted to acetyl CoA by decarboxylation. This acetyl CoA is the connecting link between glycolysis and Krebs cycle. Acetyl CoA thus formed participates in Krebs cycle and combines with oxaloacetic acid to form citric acid.
