Question 8 ATP (adenosine triphosphate): Is made within the endoplasmic reticulum of cells Is used directly for facilitated diffusion Is required to take up glucose into cells Provides the energy for creating a concentration gradient of sodium ($Na^+$) ions using primary active transport Provides the energy for creating a concentration gradient of Vitamin A using primary active transport

27. The free energy change for moving ions across a membrane depends on the concentration of the ion on each side of the membrane, membrane potential, and the ABC transporter: a, b, and c. 28. The energy for secondary active transport comes directly from the secondary active transporter hydrolyzing ATP. True or False. 29. Primary active transport is driven through harnessing the energy within a concentration gradient and/or electrochemical gradient. True or False.

What statement best explains why glucose transported across the apical membrane in intestinal epithelial cells is classified as indirect active transport? Glucose is stored in the liver, but is initially absorbed by a different organ, the small intestine. Most sugars must be digested in the mouth to generate glucose prior to absorption in the small intestine. Glucose digestion leads to the generation of ATP, and this ATP is then used to transport additional glucose. Glucose is transported both into and out of intestinal epithelial cells without consuming ATP. The formation of a glucose gradient requires a pre-existing sodium ion gradient. Question 17 Your friend works in a biotechnology company and has discovered a drug that blocks the ability of Ran to exchange GDP for GTP. What is the most likely effect of this drug on nuclear transport? Importin would be unable to bind cargo. Importin would be unable to enter the nucleus. Importin would be unable to release their cargo in the nucleus. Importin would interact irreversibly with the nuclear pore fibrils.
