Name the enzyme which catalyses substrate level phosphorylation in glycolysis -: (A) Glyceraldehyde 3 phosphate dehydrogenase, (B) Enolase, (C) Pyruvate kinase, (D) Phosphofuctokinase I
Answer is C. 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
