Question

glycolysis: produces pyruvic acid. consumes a sugar. all of the above. results in the production of nadh. results in the production of atp.

Explanation:

Glycolysis is the metabolic pathway that breaks down glucose (a sugar). One glucose molecule is converted into two pyruvic acid molecules. During this process, NADH is produced as a result of the oxidation of glyceraldehyde - 3 - phosphate. Also, a net gain of 2 ATP molecules occurs (4 ATP are produced in total, but 2 are consumed in the early steps of glycolysis). So, all the statements (produces pyruvic acid, consumes a sugar, results in the production of NADH, results in the production of ATP) are correct.

Answer:

C. all of the above.
