The enzyme is Glyceraldehyde-3-phosphate-dehydrogenase. (GAPDH). It is the enzyme that converts Glyceraldehyde-3-phosphate to D-glycerate 1,3-bisphosphate; the sixth Glycolytic pathway for breaking down glucose to ethanol, C02 in Glycolysis. This enzyme requires inorganic phosphate as substrate for the catalytic reaction to proceed. <u>Since enzymatic reactions take place by forming enzyme-substrate complexes</u>, absence of the inorganic phosphate substrate ; stops the conversion and progress of fermentation .
