Question

Why can the enzyme maltase, which breaks down into the sugar maltose, not also be used to break down the sugar sucrose?

Answer 1

The enzyme maltase breaks down disaccharide maltose into simple sugar glucose, which is usable by the body. This glucose can now also be stored in the liver for future use.

This maltase does nor break down sugar sucrose because it is the sucrase enzyme that breaks down sucrose into glucose and fructose.
