The graph below shows the concentration of the reactants and products over time for a biochemical reaction that is catalyzed by an enzyme. Which diagram best illustrates how the reaction would be affected if a competitive inhibitor that binds to the enzyme was introduced? Image depicts a graph showing the concentration of reactants and products for a chemical reaction over the course of eight minutes. Over time, the concentration of the reactants decreases and the concentration of the products increases.

KEY:
Line A = Reactants
Line B = Products

Image depicts a graph showing the concentration of reactants and products for a chemical reaction over the course of eight minutes. Over time, the concentration of the reactants (line A) decreases and the concentration of the products (line B) increases, but it occurs much more quickly than it did before the inhibitor was introduced.

KEY:
Line A = Reactants
Line B = Products

Over time, the concentration of the reactants (line A) increases and the concentration of the products (line B) decreases. The changes in concentration occur much more quickly than before the inhibitor was introduced.

Image depicts a graph showing the concentration of reactants and products for a chemical reaction over the course of eight minutes. Over time, the concentration of the reactants, line A, decreases and the concentration of the products, line B, increases. The changes in concentration occur much more slowly than before the inhibitor was introduced.

Line A = Reactants
Line B = Products
