Answer:
ATP
Explanation:
Glycolysis (from the Greek glykos, sugar, and lysis, breaks down) is an anaerobic process, that is, without the presence of oxygen, which causes the degradation of glucose (C6H12O6). In this metabolic pathway, which occurs in the cytoplasm of the cells of all living beings, the formation of pyruvic acid (C3H4O3) and ATP molecules occurs. For this reason we can say that ATP is the correct answer to your question.
The unstable glucose molecule, when broken, forms two molecules of pyruvic acid and generates four molecules of ATP. As phosphates from two ATP molecules are used at the beginning of the process, the net balance is two molecules.
