transmembrane proteins correct answers Maltase, Lactase and Sucrase are all ________________________ that function as enzymes to break down their respective disaccharide. hepatic portal vein correct answers Where would you expect to find blood that is Oxygen poor, but nutrient rich? Glut2 on the basilar side of the enterocytes correct answers How does glucose get into the hepatic portal system? False correct answers Lipase converts triglycerides into a monoglyceride and 2 molecules of fatty acids in the unstirred layer of the small intestines. (t or f) apical correct answers 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 correct answers 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 correct answers The products of the disaccharideas described in the statement enter the ______________ and are converted to _________________ in hepatocytes. afferent arteriole correct answers Smooth muscle concentration in the _______________ would decrease Glomerular Filtration Rate (GFR) thick segment of ascending limb correct answers Blocking the Na+/K+/2Cl- transporter with the diuretic furosemide (Lasix) would occure in the CO2 from HCO3- and H+ correct answers In the pulmonary capillaries, carbonic anhydrase in erythrocytes predominantly generates:
