Question

graphs show the same reaction with and without an enzyme. which statement identifies the graph with the enzyme? graph b, because the enzyme binds to the reactant, lowering the activation energy needed for the reaction to occur graph a, because the enzyme combines with the reactant molecule, producing a different end product graph b, because the enzyme absorbs the energy from the reactant, increasing the speed of the reaction graph a, because the enzyme releases energy from the reactant, changing the amount of product formed

Explanation:

Enzymes are biological catalysts that lower the activation - energy of a reaction. By binding to the reactant (substrate), they make it easier for the reaction to occur. A lower activation - energy is represented by a shorter vertical distance from the reactant energy level to the peak of the energy curve. In the given graphs, the graph with the lower activation - energy is the one with the enzyme.

Answer:

Graph B, because the enzyme binds to the reactant, lowering the activation energy needed for the reaction to occur
