What is the useful product of glycolysis for the cell?

a. nad+

b. pyruvate

c. lactic acid

d. ethyl alcohol

The correct answer is B. pyruvate

Explanation:

In glycolysis, glucose is oxidized to produce 2 molecules of NADH, ATP, and pyruvate. Then this pyruvate molecule is used in the Kreb cycle and gets fully oxidized into carbon dioxide and water.

This oxidation of pyruvate molecule gives rise to more  NADH and FADH₂ molecule. These molecules are reduced form of energy which is used as a source of electron during oxidative phosphorylation to produce more ATP molecules.

Therefore pyruvate is the useful product of glycolysis which is utilized to give energy to the cell in the form of ATP.

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.

c.           is the correct answer
