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.
