Detailed explanation-1: -Overall, glycolysis converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate.
Detailed explanation-2: -Glycolysis is a cytoplasmic pathway which breaks down glucose into two three-carbon compounds and generates energy. Glucose is trapped by phosphorylation, with the help of the enzyme hexokinase.
Detailed explanation-3: -In most cells glycolysis converts glucose to pyruvate which is subsequently oxidized to carbon dioxide and water by mitochondrial enzymes.
Detailed explanation-4: -So, the correct answer is Pyruvate.
Detailed explanation-5: -The three-carbon pyruvate molecule produced during glycolysis is converted to a two-carbon molecule of Acetyl CoA within the mitochondria.
