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.
done

Explanation:

At the saturation point, all enzyme active sites are occupied by substrate. Increasing substrate concentration beyond this point doesn't provide more available active sites for the substrate to bind to (since they're already full), so the reaction rate remains unchanged as the rate - limiting factor is now the enzyme concentration (or other factors like enzyme activity), not substrate concentration.

Answer:

There would be no effect.
