The end product of glycolysis is pyruvate, which can be used in aerobic or anaerobic respiration. Gycolyissis is the process by which glucose is broken down with two molecules of ATP.
Glycolysis is the process that is the first phase of catabolism and is part of cellular respiration. It is needed in order for cells to continue breathing and surviving instead of floundering and becoming obsolete. When there is no oxygen available after gylcolysis has occurred, the pyruvate end product will be used in anaerobic respiration. This type of respiration takes a lot of energy from the cell and requires the cell to use many of its stored sources. When there is a presence of oxygen within the cell, the pyruvate will work using the TCA cycle to perform aerobic respiration. This type of respiration does not require as much energy and results in the cell having a higher amount of usable energy after respiration.
Glycolysis is derived from Greek origins. It literally means the breakdown of something that is sweet. Glucose is a sugar, meaning that it would generally be sweet in a non-cellular environment. The process breaks the sugar down into something that can be used in a practical sense by the cell. The process allows sugars to function within the cell.
