<h2>Increase of reaction rate</h2>
Explanation:
- It is observed that when the concentration of acetylcholine remains constant in the reaction of an aqueous solution, the speed of the enzyme-catalyzed reaction or the formation of the product increases with increasing concentrations of substrate.
- The reaction rate is directly proportional to the concentration of acetylcholine.
- At very low concentrations of acetylcholine, there is a small increase in the concentration of the substrate which results in a large increase of the rate in reaction.
