Exercise 7

In an enzymatic reaction:
A)the enzyme leaves the reaction chemically unchanged.
B)if the enzyme molecules approach maximal rate, and the substrate is continually increased, the rate of the reaction does not reach saturation.
C)in the stomach, enzymes would have an optimal activity at a neutral pH.
D)increasing temperature above the optimal value slows the reaction rate.
E)the least important level of organization for an enzyme is its tertiary structure.
