Which of the following statements accurately describes the function of a metabolic pathway involved in cellular respiration? A. The function of glycolysis is to begin catabolism by breaking glucose into two molecules of pyruvate, with a net yield of two ATP. B. The function of the citric acid cycle is the transfer of electrons from pyruvate to NADH to O2. C. The function of the bonding of acetic acid to the carrier molecule CoA to form acetyl CoA is the reduction of glucose to acetyl CoA.

A. The function of glycolysis is to begin catabolism by breaking glucose into two molecules of pyruvate, with a net yield of two ATP

Explanation:

Glycolysis is the process in which glucose is broken down to pyruvate in order to produce energy. It occurs in cytosol and it can be divided into two phases: phase that requires energy (two ATP molecules are used) and phase that produces energy (four ATP molecules together with two NADH are produced).

After the glycolysis, which is the first step in cellular respiration, final products (two pyruvats) are further used. The next steps are: pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation.
