These inhibitors check the reaction rate by occupying the active site and forming a covalent bond, are called:
Correct answer: A. Irreversible inhibitors
- A. Irreversible inhibitors
- B. Reversible inhibitors
- C. Competitive inhibitors
- D. Non-competitive inhibitors
Explanation
The correct answer is Irreversible inhibitors because these inhibitors form covalent bonds with the enzyme's active site, leading to a permanent loss of activity. In contrast, Reversible inhibitors only form transient bonds and do not permanently affect enzyme function. Competitive inhibitors compete with the substrate for the active site without forming covalent bonds, while Non-competitive inhibitors do not bind at the active site but rather at another site, making them less effective in preventing substrate binding.

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.
