1- describe three means by which enzymes can facilitate chemical reaction and state how the energy barrier of the reaction might be affected.
2- contrast the way in which metal ions, coenzymes, and prosthetic groups facilitate enzymes reactions.
3- explain why allosteric regulators often act on non-catalytic subunits and how those actions influence catalysis.
