No change occur in the rate of reaction if small amount of substrate is added.
When the substrate concentration increases from 0.4% to 0.5%, the rate of the reaction remains the same because very small amount of substrate is added.
So we can conclude that no change occur in the rate of reaction if small amount of substrate is added.

If a modest amount of substrate is introduced, the reaction's rate will somewhat increase.
The rate of the reaction also marginally increases as the substrate concentration rises from 0.4 percent to 0.5 percent because of the very little increase in substrate concentration.
Enzymes are substances that operate as catalysts in living things, controlling the pace at which chemical processes take place without changing the substance itself.
