Detailed explanation-1: -Glycolysis occurs in the cytoplasm of the cell and is present in all living organisms. In this process, glucose undergoes partial oxidation to form two molecules of pyruvic acid, in absence of oxygen. No carbon dioxide is produced in this process.

Detailed explanation-2: -The main purpose of glycolysis is to provide pyruvate for the trichloroacetic acid (TCA) cycle, not to make adenosine 5′-triphosphate. The glycolytic production of pyruvate reduces the cytosol by increasing the ratio of NADH [a reduced form of NAD+ (nicotinamide adenine dinucleotide)] to NAD+.

Detailed explanation-3: -Glycolysis results in complete oxidation of glucose into pyruvic acid.

Detailed explanation-4: -Glycolysis is the method of the breakdown of glucose into pyruvate. In this method, the glucose molecule undergoes partial oxidation and forms 2 molecules of pyruvate and a pair of ATP. It happens inside the cytoplasm of the cell.

Detailed explanation-5: -The first step in glycolysis is a priming reaction, where a phosphate group is added to glucose using ATP. This reaction is important for its ability to trap glucose within the cell.
