Characteristics of Enzyme catalyzed reaction

Experiment 1: treatment of results, explain how to find the conversion factor using A=ecl.
after converting results of absorbance to nano moles per ml draw a graph ( conc of PNP with time )
discussion : explain results in 100 word+ describe how changing the conc of enzyme would affect.

in experiment 2: using the same conversion factor convert absorbance to nano mols per ml
-draw a graph of enzyme activity (y axis) against ph ( x axis) indicate the ph optimum for the enzyme
-explanation of result
