To determine the number of molecules of pyruvic acid produced when a glucose molecule undergoes glycolysis, we need to understand the steps involved in glycolysis.
Glycolysis is the first step in cellular respiration and occurs in the cytoplasm of cells. During the process of glycolysis, a single glucose molecule is broken down into two molecules of pyruvic acid. This breakdown occurs through a series of 10 enzymatic reactions.
Therefore, the correct answer is 2.
