Textbook Question
Chapter 47, Problem 7TYK
If the fat in whole milk is ingested:
a. the stomach, with its high pH, will stimulate cells of the duodenum to hasten stomach emptying.
b. parietal cells in the stomach will absorb it.
c. in the small intestine, bile salts emulsify the fats and then lipase hydrolyzes them.
d. lactase deficiency in the small intestine would prevent its digestion.
e. microvilli will absorb the fat in the form of chylomicrons directly into the blood of the hepatic portal vein.

Which of the following statements regarding protein digestion is incorrect?
A.
The intestinal enzymes trypsin and chymotrypsin continue the chemical breakdown of polypeptides into oligopeptides.
B.
Chemical digestion of proteins is initiated in the stomach through the action of the enzyme pepsin.
C.
Mechanical digestion of proteins starts in the mouth through chewing.
D.
Di- and tripeptides enter the intestinal cells where they are broken down by peptidases into individual amino acids.
Which of the following is true about carbohydrate digestion?
A.
Cellulose and lignin found in plants are totally indigestible even with intestinal bacteria.
B.
The acidity of the stomach prevents chemical digestion of carbohydrates.
C.
Dextrin and maltose are the products of chemical digestion of starch by pancreatic amylase.
D.
Disaccharidases produced from the pancreas breaks down oligosaccharides in the intestines.
A. What is/are the primary role(s) of the large intestine? a. to complete enzymatic digestion and store indigestible material b. to initiate enzymatic digestion of carbohydrates and to store water c. to absorb water from digested material, with essentially no digestive role of its own d. to secrete water into the material that is left over after all available nutrients have been absorbed e. to digest fats A. In the intestine most nutrients are absorbed regardless of whether the body has an immediate need or shortfall of them; ie there is little control over amounts taken up – which of the following does not follow this rule? a. absorption of sodium b. absorption of water c.absorption of iron d. absorption of fat soluble vitamins e. none of the above follow this rule – close control is exerted over all of them
