Which statement correctly describes acetyl-coa? a. it connects glycolysis to the citric acid cycle. b. it connects the citric acid cycle to the electron transport chain. c. it is the product of catabolism of proteins. d. it is the product of catabolism of fats.

The correct answer is option A. It connects glycolysis to the citric acid cycle

Explanation:

Acetyl CoA plays the role of initiator of the citric acid cycle which is produced by the pyruvic acid, the end product of the glycolysis. Acetyl CoA is the link between glycolysis and the citric acid cycle.

During oxidative carboxylation, Acetyl CoA produces from two molecules and release two molecules of carbon dioxide. Acetyl CoA enters into the Krebs cycle which utilizes them and produces ATP.

Thus, the correct answer is option A.
