Enzyme Kinetics Laboratory Report

Finally KM is an approximate measure of the affinity of an enzyme for its substrate A small value of KM indicates a high affinity of the enzyme for the substrate From my graphs (1 +2) I can tell that the KM was 0 24 and therefore small This means that the enzyme acid phosphatase has a high affinity for the synaesthetic substrate PNPP This

Kinetic Activity of Alkaline Phosphatase

Alkaline phosphatase (AP) cleaves the colorless substrate 4-nitrophenylphosphate (PNPP) forming the yellow product p-nitrophenol (PNP) Like many proteins the activity of AP is seriously affected by pH and as its name suggests appears to work best at alkaline pH values In this study students will measure the reaction kinetics of
