Question: 1 / 2700

What is the function of the enzyme maltase?

Breaks down sucrose to glucose

Breaks down lactose to glucose

Breaks down maltose to glucose

Maltase is an enzyme specifically responsible for breaking down maltose, which is a disaccharide composed of two glucose molecules. When maltase acts on maltose, it hydrolyzes the bond between the two glucose units, resulting in the production of individual glucose molecules. This process is essential in carbohydrate digestion, as glucose can then be easily absorbed into the bloodstream and utilized by the body for energy.

The other options refer to different enzymes that act on other substrates. For example, the breakdown of sucrose requires sucrase, while lactose is broken down by lactase. Starch digestion involves enzymes like amylase, which converts starch into maltose before maltase can act on it. Therefore, maltase's specific function is crucial for ensuring that maltose is converted into glucose, supporting effective carbohydrate metabolism.
