This can counteract the impact of competitive inhibitors
A
Increasing the concentration of competitive inhibitors
B
Decreasing substrate conc.
C
Decreasing enzyme conc.
D
Increasing substrate conc.
Explanation: 

Detailed explanation-1: -Competitive inhibition can be reversed by increasing the substrate concentration. If the substrate predominates in the mixture, it will tend to displace the inhibitor bound to the enzyme.

Detailed explanation-2: -Competitive inhibition can be overcome by increasing the substrate concentration. Because the inhibitor and substrate are in competition for the active site, increasing substrate concentration increases the likelihood that that substrate will bind and the reaction will progress normally.

Detailed explanation-3: -Competitive inhibitors can be overcome by increasing substrate concentration. This occurs because the reversible, weak bonds between the inhibitor and enzyme can be broken when there is excess substrate present (substrate competes with the competitive inhibitors for the enzyme).

Detailed explanation-4: -In the case of competitive inhibition, the effect of the inhibitor could be reduced and eventually overwhelmed with increasing amounts of substrate. This was because increasing substrate made increasing percentages of the enzyme active.

Detailed explanation-5: -Competitive inhibition can be overcome by adding more substrate to the reaction, which increases the chances of the enzyme and substrate binding.
