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.
-)
A)
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 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 carbohydrate, and digestion took place in Monica's mouth
thanks to enzymes or proteins. The blueprint for these proteins is located
on nucleic acids
