During glycolysis, what is produced from glucose?

Glycolysis is a fundamental metabolic pathway that occurs in the cytoplasm of cells, where glucose is broken down to extract energy. The correct option identifies the key products of this process: pyruvate, ATP, and NADH.

During glycolysis, one molecule of glucose (which contains six carbon atoms) undergoes a series of enzymatic reactions. This results in the splitting of glucose into two molecules of pyruvate, each containing three carbon atoms. Pyruvate is an important intermediate that can enter other metabolic pathways, such as the citric acid cycle, under aerobic conditions or be converted to lactate under anaerobic conditions.

In addition to pyruvate, glycolysis generates ATP, which serves as a primary energy carrier in the cell. Specifically, the process yields a net gain of two ATP molecules per glucose molecule, although four ATP molecules are produced overall; two are consumed in the initial steps of glycolysis.

NADH is another crucial product that is formed during this metabolic pathway. This compound acts as an electron carrier, allowing the cell to harness energy for use in different metabolic reactions later on.

Overall, the identification of pyruvate, ATP, and NADH as the primary products of glycolysis reflects a comprehensive
