In which of the following categories do reversible inhibitors usually constitute?
Correct answer: D. Weak linkage with enzyme
- A. No Linkage with enzyme
- B. Strong linkage with enzyme
- C. Medium linkage
- D. Weak linkage with enzyme
Explanation
Inhibitors inhibit the activity of enzymes by reducing the rate of their reactions. They are found naturally but are also used artificially as drugs, pesticides, and research tools. Inhibitors that bind weakly and can be removed out easily are called reversible inhibitors. Reversible inhibitors form a weak linkage with the enzyme. Hence, D is the correct option.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
