Vedclass · Answer

(B) In non-competitive inhibition,the inhibitor does not resemble the substrate in structure and does not compete for the active site.Instead,the inhibitor binds to an allosteric site (a site other than the active site) on the enzyme.This binding induces a conformational change in the enzyme's structure,rendering the active site non-functional.Cyanide acts as a non-competitive inhibitor of cytochrome oxidase in the electron transport chain,preventing the final step of cellular respiration.
