Among the products of glycolysis, which compounds contain energy that can be used by other biological reactions?

Pyruvate, NADH, ATP

Explanation:

ATP is most abundant energy resource used to start chemical processes in biological systems and it is the main product of cellular respiration. Overall, glycolysis produces two pyruvate molecules, a net gain of two ATP molecules, and two NADH molecules. In addition, the NADH and pyruvate produced in glycolysis are used in subsequent steps of cellular respiration to make even more ATP.

Net Input: ADP, NAD⁺, Glucose

Net Output: ATP, NADH, Pyruvate

In glycolysis, the six-carbon sugar glucose is converted to two molecules of pyruvate (three carbons each), with the net production of 2 ATP and 2 NADH per glucose molecule. There is no O2 uptake or CO2 release in glycolysis.
