Question

what is the main transformation that occurs during glycolysis?
glycolysis produces atp and pyruvate by oxidizing water.
glycolysis produces atp and pyruvate by oxidizing glucose and nad+.
glycolysis produces pyruvate, atp, and nadh by oxidizing glucose.
glycolysis produces co2, atp, and pyruvate by reducing glucose.

Explanation:

Glycolysis is the process where one glucose molecule is broken - down into two pyruvate molecules. During this process, some energy is released and used to convert ADP to ATP, and $NAD^+$ is reduced to NADH. Glucose is oxidized in this process.

Answer:

Glycolysis produces pyruvate, ATP, and NADH by oxidizing glucose.
