It seems there might have been a typo or some confusion in your question. However, I can clarify the metabolic process you're referring to.
When a single glucose molecule undergoes glycolysis, it is converted into two molecules of pyruvic acid (or pyruvate). Glycolysis breaks down one glucose molecule (6 carbons) into two molecules of pyruvate (each with 3 carbons).
Thus, the answer is 2 molecules of pyruvic acid are produced from one molecule of glucose during glycolysis.
