Answer:
C. NADH
Explanation:
Glycolysis is the breakdown of glucose molecules. In this process, glucose molecule which contains six carbons are converted into 3 carbon atom which is called pyruvate molecule. This process is anaerobic which means does not require oxygen. In the end of glycolysis, two products are formed i. e. Nicotinamide adenine dinucleotide (NADH) and adenine tri phosphate (ATP) molecules.
