Which of the following statements regarding glucose transporters is true? The high Km of GLUT2 leads to more drastic glucose uptake rate changes when blood glucose concentration increases after a meal. The high Km of GLUT3 in neuronal cells leads to high rates of glucose uptake by these cells even if blood glucose concentrations are low. The Vmax for glucose import into a cell cannot be altered without changing the type of GLUT transporter expressed by the cell. GLUT1 will transport glucose, mannose and galactose with similar affinity.

Question 4 using myplate's daily food plant for 2000 kilocalories as a reference, the servings from the protein foods group in this menu are a. adequate overall, and consistent with the dietary guidelines 2010 recommendations. b. short 2 ounce equivalents. c. inadequate in terms of the recommendations for a 2000 kcal diet. d. adequate overall, but inconsistent with the dietary guidelines 2010 recommendations.

You have a solution that contains phospholipid vesicles in a test tube. these vesicles have phospholipid bilayers, but do not contain any membrane transporters. you add a number of different molecules to the solution, and wait a period of time for them to equilibrate. if you could measure the concentration of each molecule, for which of the following would you expect to measure equal concentrations inside and outside of the vesicles? assume for this question that the overall osmolarity inside and outside the vesicles is the same (that is, there is no appreciable diffusion of water across the membrane). (select two answers) an amino acid with a hydrophobic side-chain a small non-polar molecule a negatively charged ion a small polar molecule a small lipid hormone
