Correct Answer: glucose


Solution : The correct answer is glucose .

In the process of respiration, the stage known as glycolysis involves the breaking down of glucose to pyruvic acid. Glycolysis is the initial stage of both aerobic and anaerobic respiration and it takes place in the cytoplasm of the cell. During glycolysis, one molecule of glucose is converted into two molecules of pyruvic acid, producing a small amount of ATP (adenosine triphosphate) and NADH (nicotinamide adenine dinucleotide).
