Feedback inhibition O The product of a series of reactions acts as an inhibitor for an earlier reaction. Hormones control the synthesis of enzymes. A regulator binds to the enzyme at a site other than the active site. This binding changes the shape of the enzyme and alters the catalytic ability of the enzyme. An inhibitor binds reversibly to the enzymesubstrate complex, blocking the binding of the second substrate to the active śite. The activity of an enzyme is influenced by the addition or removal of a group that is covalently bonded to the enzyme. An inhibitor forms covalent bonds to the active site, permanently blocking it.

The effect of on the activity of an enzyme can usually be overcome by increasing the concentration of substrate(s). Choose the best answer the phosphorylation of the R groups of serine (S), threonine (T) and tyrosine (Y) an allosteric effector a noncompetitive inhibitor a competitive inhibitor

Catalysis through proximity and orientation effects involves: (select all that applies) Group of answer choices binding of acidic and/or basic groups in the binding site facilitating chemical reactions by binding substrates close to specific groups binding of substrate in specific, restrictive orientations depending on metal ions for catalysis
