There are several processes that take place from the moment food enters our mouth until it is completely digested and used for energy.
Using approximately 400-500 words, describe in detail and in order of process the mechanical (stomach and intestine)and chemical (gastric acid and enzymes) digestion of eating a grilled chicken sandwich with mayonnaise, lettuce, and tomatoes. Note what role the pancreas, gallbladder, and liver play in digestion of the ingredients? From what ingredients is your body deriving its energy and how many basic calories from the macronutrients ingested?
Include at least two scholarly references (using APA formatting and style) to guide your answers (note that you can use your textbook as one of your references).
Complete the following statements to describe the digestion and absorption of various nutrients. Not all choices will be used.
amino acids
Starch is a(n)
that is first broken down into
by
salivary
in the mouth.
stomach
carbohydrate
Additional digestive action in the small intestine converts maltose to
bile salts
which then can be absorbed.
lipase
Proteins are broken down into peptides in the
by
maltose
which is present in gastric juice.
mouth
Peptides are then broken down into
in the small intestine and
amylase
absorbed.
small intestine
Fats are emulsified in the small intestine by
and later digested
glucose
by
pepsin
Which of the following is/are TRUE about where the following macromolecules are digested and absorbed by the body?
-Carbohydrates are digested by enzymes in the mouth and the small intestine and are absorbed in the small intestine
-Three of these answers are correct
-Proteins are digested by enzymes in the stomach and the small intestine, and absorbed in the small intestine
-Water is absorbed in the stomach and reabsorbed in the large intestine
-Two of these answers are correct
