How do the substrate concentrations affect the enzyme activity?

Factors Affecting Enzyme Activity

How does pH affects the rate of enzyme activity?

Among the statement given below, which statements /s is / are correct regarding the relationship between enzyme and substrate ? I. Above a certain concentration of substrate , an enzyme reaches its maximum rate of reaction II. Increasing the substrate concentration to a higher level doesn't reverse the effects of a competitive inhibitor. III At high substrate concentration , a non competitive inhibitor no longer affects the enzyme activity . IV. The higher the concentration of substrate the faster an enzyme can cataylse a reaction.

The Given figure shows three velocity-substrate concentration curves of an enzyme reaction. What do the curves X Y and Z depict respectively ?
