The reason an increase in substrate concentration does not increase the reaction rate indefinitely is because
A) eventually the enzyme will no longer recognize the substrate.
B) the active site will become saturated with substrate and the enzyme will not be able to go any faster.
C) another enzyme will take advantage of the excess substrate and use it for a different reaction.
D) enzymes cannot be used more than once in a reaction.
E) the enzyme will become denatured.

Question

Once the active site of an enzyme becomes saturated with substrate, it cannot process any more substrates and thus the reaction rate cannot increase further.
