Question

during cellular respiration, four total atp are produced when pyruvic acid is created. what else is produced as a result of this reaction? (1 point)
oxygen
sugar
heat
water

Explanation:

The reaction described is glycolysis, the first stage of cellular respiration where pyruvic acid (pyruvate) is formed. Glycolysis produces a net 2 ATP (with a total of 4 ATP generated), 2 NADH, and also releases heat as cellular respiration is not 100% efficient, with energy lost as thermal energy. Oxygen is a reactant, sugar is the starting molecule, and water is produced in the final electron transport chain stage, not during pyruvic acid formation.

Answer:

heat
