This ability is brought about by a genetic mutation that causes ... February 25, 2020 - When the enzyme has attached to the substrate, the molecule is called the enzyme-substrate complex. For example, the sugar found in milk is called lactose. With the aid of the enzyme, lactase, the substrate, lactose, is broken down into two products, glucose and galactose. The reaction that takes place when you digest lactose involves splitting lactose into its two components, glucose and galactose. Glucose and galactose are bonded together in the lactose molecule, and lactase assists in the process of separating them through a mechanism called hydrolysis, which means "splitting with water."
