Problem: Enzymes are active in all cells as well as in the digestive system. Lactase is found in the digestive system, and is one of many exzymes in mammalian intestines that help break down food molecules into pieces small enough to be absorbed into our cells. Specifically, lactase breaks the sugar lactose, a disaccharide, into 2 monomers, glucose and galactose. Model 1: Lactase breaks won lactose. Using the names of the reactants and products (instead of chemical formulas), write a chemical equation for the reaction catalyzed in Modal 1. Hint: only reactants and products are included in a chemical reaction. Need Assignment Help?
