Sugars usually end in -ose (lactose, sucrose, fructose). So sucrase is an enzyme which acts on sucrose. In this case, the action is to break it down. Lactase is an enzyme which acts on lactose - in this case, the action is to break lactose down. One metabolic enzyme is pyruvate dehydrogenase. This is an enzyme which acts on pyruvate, and the action is to remove a hydrogen molecule. Just an example of an action that is not food breakdown.
