Explanation:
Detailed explanation-1: -Pyruvate-three carbons-is converted to acetyl CoA, a two-carbon molecule attached to coenzyme A.
Detailed explanation-2: -Pyruvic acid is the formed product (end) of glycolysis, a process that breaks down glucose (a 6-C molecule) into two molecules of pyruvate (a 3-C molecule) and simultaneously yields adenosine triphosphate (ATP), which powers cellular function.
Detailed explanation-3: -A single glucose molecule, which is the starting material for glycolysis, contains six carbon atoms. Glycolysis produces two pyruvate molecules, and one pyruvate molecule contains three carbon atoms.
Detailed explanation-4: -The three-carbon molecule that is the final product of glycolysis is pyruvate.
