Here are the % Protein for each fraction
Fraction P-1 % = (60/307) x 100 % = 19.5%
Fraction P-2 % = (40/307) x ...
Solution contains the % Protein for each fraction, the enzyme activity in nmoles/min/ml and a graph plotted with the % protein (independent variable x) versus the enzyme activity in nmoles/min/ml (dependent variable y).
