Suppose that an earthquake hits. Which of the following would be most likely to characterize your books being scattered on the floor all over your room?

Enzymes alter the equilibrium point of a reaction.

All enzymes are proteins.

Match each definition with the corresponding term. -substrate A)primary coupling agent in cellular reactions B)addition of a phosphate group to a target molecule C)product of the reaction interacts with an enzyme in a noncompetitive way to inhibit or enhance enzyme activity D)linking of an exergonic reaction with an endergonic reaction that allows a cell to drive a nonspontaneous reaction to completion E)series of chemical reactions where the products of one reaction are the reactants for a subsequent reaction F)substance that facilitates a chemical reaction without itself being consumed by the reaction G)energy needed to start a reaction, be it endergonic or exergonic H)portion of the enzyme that binds to a reactant or reactants I)state in which the rate of the forward reaction equals the rate of the reverse reaction J)intermediate arrangement of unstable bonds between atoms that can proceed toward either the reactants or the products of a reaction K)reactant molecule that binds to an enzyme
