Question

Drugs which bind strongly to the active site of an enzyme and do not depend upon the concentration of natural substrate are called as:

• A. competitive inhibitors
• B. non-competitive inhibitors
• C. $\beta$-blockers
• D. $\alpha$-blockers

Competitive inhibitors are the interruption of a chemical pathway owing to one chemical substance inhibiting the effect of another by competing with it for binding or bonding.

These drugs bind to active sites and do not depend on the concentration of natural substrate.
