An allosteric inhibitor does which of the following?

Binds to an enzyme away from the active site and changes the conformation of the active site, increasing its affinity for substrate binding

Binds to the active site and blocks it from binding substrate

Binds to an enzyme away from the active site and changes the conformation of the active site, decreasing its affinity for the substrate
