Explanation:
Detailed explanation-1: -Pyruvate-three carbons-is converted to acetyl CoA, a two-carbon molecule attached to coenzyme A .
Detailed explanation-2: -The breakdown of glucose, a six-carbon molecule, into a three-carbon molecule called pyruvate takes place in the cytoplasm.
Detailed explanation-3: -Each Acetyl CoA consists of 2 carbon atoms. During glycolysis, two molecules of pyruvic acid, a 3-carbon atom molecule, formed and undergo oxidative decarboxylation in presence of coenzyme A to produce the Acetyl CoA complex.
Detailed explanation-4: -The three-carbon molecule that is the final product of glycolysis is pyruvate.
