Many apoenzymes are inactive by themselves and must be activated by cofactors and/or coenzymes ATP holoenzymes substrates

cofactors and/or coenzymes

Inhibitors that fill the enzyme's active site and compete with the normal substrate are noncompetitive allosteric competitive ribosomal

competitive
