Explore how food is processed by the body! Demonstrate how complex food molecules break down into simpler chemicals with the aid of digestive enzymes. Your students will learn about the characteristics of such enzymes as well as the parts of the digestive system and their respective functions. They’ll treat common foods - such as carbohydrates, lipids, proteins, and others - with various digestive enzymes and identify their subunits. Class size - 40 students.
