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.
Responses
A The saltine is made of flour, a carbohydrate. The flour dissolved in the saliva found in Monica's mouth, which is mostly water.The saltine is made of flour, a carbohydrate. The flour dissolved in the saliva found in Monica's mouth, which is mostly water.
B The saltine is mostly flour, a carbohydrate. The bonds of the carbohydrate were broken down by an enzyme in Monica's mouth, which is a lipid.The saltine is mostly flour, a carbohydrate. The bonds of the carbohydrate were broken down by an enzyme in Monica's mouth, which is a lipid.
C The saltine is a combination of carbohydrate and lipid; enzymes or proteins in Monica's digestive tract broken down the bonds of the two macromolecules in the saltine.The saltine is a combination of carbohydrate and lipid; enzymes or proteins in Monica's digestive tract broken down the bonds of the two macromolecules in the saltine.
D The saltine is a carbohydrate. and digestion took place in Monica's mouth thanks to enzymes or proteins. The blueprint for these proteins is located on nucleic acids
