A graph of product versus time (as in Figure 6.2 in your textbook) for an enzyme is determined to be hyperbolic. Why does the amount of product level off as time increases?
A) The reaction has reached equilibrium; that is, the forward and reverse reactions are occurring at a fixed rate.
B) There is a product inhibition of the enzyme.
C) The reaction runs out of reaction materials.
D) The enzyme has finished accelerating the reaction.
E) None of the above.

A hyperbolic graph typically indicates that the reaction is reaching equilibrium, meaning that the forward and reverse reactions are occurring at a fixed rate. Therefore, the amount of product levels off as time increases. Option B is not necessarily true for all hyperbolic graphs, option C is not relevant as it is not related to the shape of the graph, and option D is a possible explanation but not the best one for a hyperbolic graph.
