During glycolysis, glucose is broken down into two molecules of pyruvate.

A diagram shows the conversion of a glucose molecule to 2 pyruvic acid molecules. In this process, 2 A T P form 2 A D P, 2 N A D produce 2 N A D H, and 4 A D P produce 4 A T P.

What is the main transformation that occurs during glycolysis?

Glycolysis produces ATP 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.

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

Explanation:

Glycolysis is an oxidation reaction in which glucose reacts with oxygen molecules and oxidized. By oxidizing glucose, it produces pyruvate, adenosine triphosphate (ATP) and nicotinamide adenine dinucleotides (NADH). Glycolysis has two phases. In the first phase, 2 ATP molecules are invested for the phosphorylation of glucose to break down into a simpler one. In the second phase of glycolysis, 4 ATP molecules are earned back with 2 NADH and a simpler form of glucose (6C) to pyruvate (3C) by oxidizing glucose.

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

Explanation:

Glycolysis is the breakdown of glucose which has six carbon atoms to two molecules of pyruvic acid which have three carbon atoms each. Glycolysis is independent of the presence of oxygen although its rate may increase when there is a deficiency of oxygen in aerobic cells. The result of glycolysis is the formation of two molecules of pyruvate, two molecules of ATP and NADH.
