Final answer:
Pyruvate is the carbon-containing compound produced by glycolysis.
Step-by-step explanation:
The carbon-containing compound produced by glycolysis is pyruvate. During glycolysis, glucose is broken down into two molecules of pyruvate. Pyruvate then enters the mitochondria, where it is converted to acetyl CoA, a two-carbon compound, which then enters the Krebs cycle. Pyruvate is formed in the cytoplasm and contains three carbon atoms.
