Which of the following statements regarding enzyme inhibition is corre...
Competitive Inhibition vs. Non-competitive Inhibition:
Competitive inhibition occurs when a molecule, known as the inhibitor, competes with the substrate for binding to the active site of the enzyme. This type of inhibition can be overcome by increasing the concentration of the substrate because the substrate can outcompete the inhibitor for binding to the enzyme's active site.
Explanation of Correct Statement:
In the context of enzyme inhibition, the statement that says "Competitive inhibition is seen when the substrate and the inhibitor compete for the active site on the enzyme" is correct. This means that in competitive inhibition, the inhibitor molecule is structurally similar to the substrate and binds to the active site of the enzyme, preventing the substrate from binding. As a result, the enzyme's activity is reduced because the substrate cannot access the active site due to the presence of the inhibitor. However, by increasing the concentration of the substrate, the chances of the substrate binding to the enzyme and carrying out the reaction are enhanced, thereby overcoming the competitive inhibition effect.
In summary, competitive inhibition involves the competition between the substrate and the inhibitor for the active site of the enzyme, and it can be reversed by adding more substrate to outcompete the inhibitor.
