Which of the following descriptions about enzyme inhibitors is incorrect?
|
|
Inhibitors cause a decrease in the rate of enzymatic reactions.
|
|
|
All inhibitors block the entry of substrates into the active sites.
|
|
|
Cyanide and mercury are examples of enzyme inhibitors.
|
|
|
Some inhibitors are used by humans as drugs to treat diseases.

Explanation:
Detailed explanation-1: -(e) Assertion is wrong statement reason is correct statement. Assertion (A) Competitive inhibitors compete with natural substrate for their attachment on the active sites of enzymes. Reason (R) In competitive inhibition, inhibitor binds to the allosteric site of the enzyme.
Detailed explanation-2: -So, the correct answer is ‘Competitive inhibition is seen when the substrate and the inhibitor compete for the active site on the enzyme. ‘
Detailed explanation-3: -The competitive inhibitor does not affect the rate of breakdown of the enzyme-substrate complex.
Detailed explanation-4: -Competitive inhibition. Blocking enzyme action through blocking its active sites is competitive inhibition.
