Arrange the events for the hydrolysis of amide bonds by chymotrypsin in their correct order. attack by ser 195 to give a tetrahedral intermediate protonation by his 57 and release of the free c-terminus of the hydrolyzed bond protonation by his 57 and release of the free n-terminus of the hydrolyzed bond attack by water, leading to formation of a tetrahedral intermediate binding of substrate to properly position the scissile bond for cleavage

Ithink that the answer is b

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
