BMS 300 EXAM 4 CSU QUESTIONS ANDVERIFIED ANSWERS
transmembrane proteins - ANSWER Maltase, Lactase and Sucrase are all
________________________ that function as enzymes to break down their
respective disaccharide.
hepatic portal vein - ANSWER Where would you expect to find blood that is
oxygen-poor, but nutrient-rich?
Glut2 on the basilar side of the enterocytes - ANSWER How does glucose get
into the hepatic portal system?
False - ANSWER Lipase in the unstirred layer of the small intestines converts
triglycerides into a monoglyceride and 2 molecules of fatty acids. (t or f)
apical - ANSWER The Na+-driven co-transporters for glucose and amino
acids are located on what side of the membrane?
duct, from the lumen into epithelial cell - ANSWER The ability to digest the
milk sugar lactose is unique to mammals. At the time of weaning, this gene is
normally turned off by a regulatory gene located upstream from the lactase
gene. A single base change in the regulatory gene can prevent it from
inactivating the lactase gene and permit the persistence of lactase expression
into adulthood. These spontaneous mutations in the regulatory gene have
happened independently in a number of human populations. About 8000 years
ago such a mutation took place in one individual in central Northern Europe.
This person and his or her descendents had such a selective advantage that in
some Northern European populations 90- 95% of the population have the
mutant regulatory gene. In two East African cultures, single nucleotide changes
, in the regulatory gene, which are distinct from one another and different from
the European mutation have imparted lactase persistence in these populations.
From the reading you would predict that the CFTR proteins would be found on
_______________ cells where they function in a complex with ENaCs to
transport chloride _______________ in sweat and salivary glands.

effect is the result of ____________________.
