Lactase is a protein enzyme that digests (breaks down) lactose (milk sugar) into glucose and. galactose (smaller sugars). The chemical equation below illustrates what happens when the. enzyme lactase digests lactose (milk sugar).
How Enzymes work. 1. Enzymes catalyse only those reactions that happen naturally. 2. Enzymes are specific: each enzyme is responsible for only 1 kind of reaction, because they are shaped to work with only a certain substrate that matches enzyme's active site. 3. Enzyme changes its conformation when substrate bonds to its active site.
