The image shows the rate of an enzyme reaction under conditions of no inhibition, competitive inhibition, and noncompetitive inhibition as reactions labeled uninhibited, A, and B. Which of the following best explains what has occurred in the enzyme reactions? A-Reaction B shows competitive inhibition, where increased substrate competes with inhibitors for the active site.
b-Reaction A shows noncompetitive inhibition, where increased substrate competes with inhibitors for the active site.
c-Reaction A shows competitive inhibition, where increased substrate does not affect the enzyme’s binding with the inhibitor.
d-Reaction B shows noncompetitive inhibition, where increased substrate does not affect the enzyme’s binding with the inhibitor.
