Glycolysis

-glycolysis is an anaerobic process

-Occurs in the cytoplasm

-Glycololysis (gli KAH lih sis) is a series of chemical reactions in the cyto­ plasm of a cell that break down glucose, a six-carbon compound, into two molecules of pyruvic (pie RUE vik) acid, a three-carbon compound. Because two molecules of ATP are used to start glycolysis, and only four ATP molecules are produced, glycolysis is not very effective, producing only two ATP molecules for each glucose molecule broken down.
