BMS 300 Exam 4 [2026/2027] | UPDATED
ACTUAL Exam Question and Answer | A+
Verified
• hepatic portal vein -✓✓ Where would you expect to find blood that is Oxygen
poor, but nutrient rich?
• Glut2 on the basilar side of the enterocytes -✓✓ How does glucose get into the
hepatic portal system?
• False -✓✓ Lipase converts triglycerides into a monoglyceride and 2 molecules of
fatty acids in the unstirred layer of the small intestines. (t or f)
• apical -✓✓ 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 -✓✓ 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 occurred independently in several human
populations. About 8000 years ago such a mutation occurred in one individual in
central Norther Europe. This individual and his or her offspring 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, singl
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.
, Based on the passage, you would expect the CFTR proteins to be located on
_______________ cells where they work in conjunction with ENaCs to facilitate
the movement of chloride _______________ in sweat and salivary glands.
• hepatic portal blood, glycogen -✓✓ The products of the disaccharideas described
in the statement enter the ______________ and are converted to
_________________ in hepatocytes.
• afferent arteriole -✓✓ Smooth muscle concentration in the _______________
would decrease Glomerular Filtration Rate (GFR)
• thick segment of ascending limb -✓✓ Blocking the Na+/K+/2Cl- transporter with
the diuretic furosemide (Lasix) would occure in the
• CO2 from HCO3- and H+ -✓✓ In the pulmonary capillaries, carbonic anhydrase
in erythrocytes predominantly generates:
• lower motor neurons, spinal cord, skeletal muscle -✓✓ The diaphragm is
innervated by _________________________ whose neuronal cell bodies are
located in the ____________________ and innervate ______________________.
• same as, elastic recoil -✓✓ Following a pneumothorax where a penetrating
wound has opened the pleural sac the lung collapses because the intrapleural
pressure is _________________ the atmospheric pressure. The effect is the result
of ____________________.
• arterial -✓✓ The peripheral chemosensors that can affect breathing rate monitor
CO2 and O2 in _____________ blood
