JEE Main levelSingle correct optionDifficulty 2 of 3bm125
A competitive inhibitor of an enzyme
Abinds away from the active site and its effect is unaffected by [S].
Bpermanently destroys the enzyme by cleaving its peptide bonds.
Cresembles the substrate and binds to the active site, and its effect can be reduced by increasing [S].
Dincreases the activation energy by changing the equilibrium constant.
Answer: C
A competitive inhibitor has a structure similar to the substrate and competes for the active site. A large excess of substrate outcompetes it, restoring the rate.
