Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Increasing the substrate concentration in an enzymatic reaction could overcome which of the following?
A
allosteric inhibition
B
competitive inhibition
C
noncompetitive inhibition
D
denaturization of the enzyme
Explanation: 

Detailed explanation-1: -Competitive inhibition is when an inhibitor molecule competes with the substrate for the active site on the enzyme. Increasing substrate concentration can overcome inhibition from a competitive inhibitor.

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 inhibition can be overcome by adding more substrate to the reaction, which increases the chances of the enzyme and substrate binding.

Detailed explanation-4: -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-5: -Increasing the substrate concentration in an enzymatic reaction could overcome which of the following? cofactor necessary for enzyme activity. changing the shape of the enzyme active site. feedback inhibition.
