Regarding the physical condition (characteristics of the solution/environment) in which an enzyme finds itself: sometimes enzymes are most active at a certain level and still active but to a lesser degree at a level above or below the optimal level. Describe the likely reason for the enzyme’s decrement in function at levels other than the optimal level?
Using enzyme kinetics, illustrate the cooperative behavior of allosteric enzymes (plot of reaction velocity versus substrate concentration for instance)
