Name the enzyme which catalyses substrate level phosphorylation in glycolysis -
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
Carbohydrates
Glyceraldehyde 3 phosphate dehydrogenase
Enolase
Pyruvate kinase
Phosphofuctokinase I
Pyruvate kinase
