Question

During cellular respiration one molecule of glucose is broken down into two molecules of

Answer 1

One Glucose (C6H12O6) is broken down to 2 molecules of pyruvic acid. Results in the production of 2 ATPs from each glucose molecule.

Answer 2

During cellular respiration, one molecule of glucose is broken down into two molecules of pyruvate (pyruvic acid)

• The word glycolysis implies glucose splitting, which is precisely what occurs in the first stage of cellular respiration (Glycolysis). Enzymes split one molecule of glucose into two molecules of pyruvate which is also known as pyruvic acid.

• In the glycolysis stage, Glucose is split into two 3-carbon pyruvate molecules which results in the release of energy and which is transferred to ATP.

• These two molecules of pyruvic acid move on to Stage II of cellular respiration. The energy for splitting glucose is provided by two molecules of ATP.

Hence, During the stage of glycolysis, one glucose molecule is split into two pyruvate molecules by using 2 ATP and then resulting in the production of 4 ATP and 2 NADH molecules.
