Question

what would happen to the rate of a reaction if the concentration of substrate was increased after the point of saturation?
the reaction rate would increase.
the reaction rate would decrease.
there would be no effect.

Explanation:

Enzymes catalyze reactions. At saturation, all enzyme active sites are occupied. Increasing substrate beyond this (when enzymes are fully engaged) doesn't change reaction rate as enzymes can't process more substrate at once.

Answer:

There would be no effect.
