Answer: The chemical reaction in this example is Called hydrolysis in the presence of Lactase
Here is a word equation for the hydrolysis of lactose:
lactose + water → galactose + glucose
Explanation: The equation is called <hydro> + <lysis) of these terms refer to water and splitting respectively. So hydrolysis means splitting with water. Enzymes pull out a monomer by examining where the monomers are connected, and placing a water molecule in between them, resulting in the breakage of the bond between the monomers. Here are two picture to represent it.
