Question

Students in biology are studying the macromolecules of life. They used a calorimeter to determine the calories in various types of food. Once the lab was completed, the students ate the left over food samples. Monica commented that in just 6 or 7 "chews" of the saltine, it was gone; nothing but a sticky paste in her mouth. Elaborate on what happened chemically while chewing the saltine. Include the macromolecules present.
