Concept introduction: In the glycolysis metabolic pathway, a glucose molecule breaks down into two pyruvate molecules. Two ATP molecules and NADH reduced coenzymes are produced in the glycolysis pathway.
The molecule that contains six carbon atoms is termed as a
(d)
Interpretation: To determine the number of
Concept introduction: Lactate dehydrogenase enzymes convert pyruvate to lactate under anaerobic conditions in the human body. This anaerobic reduction of pyruvate to form lactate by enzymes is called lactate fermentation. The overall reaction equation for the conversion of pyruvate to lactate is as follows:
The molecule that contains six carbon atoms is termed as a
