What is the three-carbon end product produced from glycolysis?

Explanation:
Glycolysis ends by breaking glucose (six carbons) into two molecules that each have three carbons, called pyruvate. So the three-carbon end product produced from glycolysis is pyruvate. Under aerobic conditions, pyruvate can go on to become acetyl CoA for the TCA cycle; under anaerobic conditions, it can be reduced to lactate to keep glycolysis running. Oxaloacetate has four carbons and acetyl CoA has two, so they aren’t the direct end product of glycolysis, and lactate is formed from pyruvate after glycolysis, not produced directly by glycolysis itself.
