<prompt> Name the enzyme which catalyses substrate level phosphorylation in glycolysis -Glyceraldehyde 3 phosphate dehydrogenaseEnolasePyruvate kinasePhosphofuctokinase I  <response>: Ans. is c i.e., Pyruvate kinase In substrate level phosphorylation, at the level of substrate itself energy that is liberated is trapped in the form of ATP. To make it simple, in a chemical freaction, if a substrate is converted into products and simultaneously, ADP is converted into ATP, it is considered as substrate level phosphorylation. There are four substrate level phosphorylation steps in human metabolism
