Question

Which of the following statements accurately describes the function of a metabolic pathway involved in cellular respiration?a. the function of the citric acid cycle is the transfer of electrons from pyruvate to NADH to O2b. the function of the bonding of acetic acid to the carrier molecule CoA to form acetyl CoA is the reduction of glucose to acetyl CoAc. the function of glycolysis is the begin catabolism by breaking glucose into two molecules of pyruvate, with a net yield of two ATP

Answer 1

Answer:

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 very first step of cellular respiration. It breaks down glucose into two molecules of pyruvate. During glycolysis, 2 molecules of ATP and 2 molecules of NADH are formed. Pyruvate enters the TCA cycle in the form of acetyl CoA.  

The NADH formed in glycolysis and TCA cycle enter oxidative phosphorylation to drive ATP synthesis.  

Hence, glycolysis serves to start the process of cellular respiration.
