The term glycolysis has originated from the Greek words 'glycos' for sugar and 'lysis' for splitting. The scheme of glycolysis was given by Gustav Embden, Otto Meyerhof, and J. Parnas and is often referred to as the EMP pathway. In anaerobic organisms, it is the only process in respiration. 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.
