gly·co·gen·e·sis

the formation of glycogen from sugar.

Glycogenolysis is the process by which the glycogen present in the liver is transformed into glucose, to be released into the blood

Gluconeogenesis (GNG) is a metabolic pathway that results in the generation of glucose from non-carbohydrate carbon substrates such as pyruvate, lactate, glycerol, and glucogenic amino acids. While primarily odd-chain fatty acids can be converted into glucose, it is possible for at least some even-chain fatty acids.

GLYCOLYSIS. : the enzymatic breakdown of a carbohydrate (as glucose) by way of phosphate derivatives with the production of pyruvic or lactic acid and energy stored in high-energy phosphate bonds of ATP
