Conversion of fructose 1, 6-bisphosphate to glyceraldehyde 3 phosphate and dihydroxyacetone phosphate, is catalysed by Aldolase. Both contain 3 carbon atoms and are functional isomers.Mutase helps in conversion of 3 - phosphoglyceric acid to 2-phosphoglyceric acid. In the presence of enzyme glyceraldehydephosphate dehydrogenase, two molecules of glyceraldehyde 3-phosphate loses hydrogen to 2NAD+ to form 2NADH+H+ and accepts inorganic phosphate to form two molecules of 1, 3 - diphosphoglyceric acidGlucose enters the glycolytic pathway by phosphorylation (addition of phosphate). Glucose is phosphorylated to glucose-6-phosphate by ATP in the presence of enzyme hexokinase and Mg2+.
