Detailed explanation-1: -Glycolysis ultimately splits glucose into two pyruvate molecules. One can think of glycolysis as having two phases that occur in the cytosol of cells. The first phase is the “investment” phase due to its usage of two ATP molecules, and the second is the “payoff” phase.

Detailed explanation-2: -Glycolysis (gly-KOL-ih-sis), which means “sugar splitting, ” is the name for the metabolic pathway that breaks a 6-carbon glucose molecule into two 3-carbon pyruvate molecules. The glycolysis pathway involves 10 separate protein enzymes, and it is present in most of the body’s cells.

Detailed explanation-3: - During glycolysis, glucose is broken down in ten steps to two molecules of pyruvate, which then enters the mitochondria where it is oxidised through the tricarboxylic acid cycle to carbon dioxide and water. Glycolysis can be split into two phases, both of which occur in the cytosol.
