What three-carbon structure is formed by splitting a glucose molecule?

Explanation:
Glycolysis splits a six-carbon glucose molecule into two three-carbon molecules, called pyruvate. This is the direct product of the cleavage step in glycolysis and sets up the next stages of cellular respiration. Acetyl CoA is a two-carbon unit used after pyruvate is processed for entry into the citric acid cycle. Lactate is formed from pyruvate under low-oxygen conditions, not directly from glucose splitting. Oxaloacetate is a four-carbon molecule involved in the citric acid cycle, not a direct split product of glucose. So the three-carbon structure formed by splitting glucose is pyruvate.
