The enzymes alter the rate of a reaction. Give reason. With the help of a graph, compare the rate of an enzymatic reaction with a non-enzymatic reaction.

Solution

Enzyme speed up the rate of reaction, enzyme is a biological molecules made of protein, it binds with other molecules in the reaction to produce a new molecule that helps speed up the reaction. However, enzymes are highly selective- meaning, it only speed up a specific chemical reaction.
