Which of the following statements about membrane transport in the intestinal epithelial cell is CORRECT? a) The transport of glucose at the basolateral plasma membrane occurs by facilitated diffusion (passive transport). b)If ATP levels are eliminated in intestinal epithelial cells, this will not affect the transport of glucose, either in the short or longer term. c) The transport of glucose at the apical plasma membrane is a form of facilitated diffusion (passive transport). d) The transport of glucose at the apical plasma membrane is considered a form of primary active transport. e) The transport of Na+ at the basolateral plasma membrane is a form of facilitated diffusion. The negative membrane potential of cells at rest (which of the following is correct) a) is generated in large part by a certain type of K+ channel that supports passive diffusion of K+. b)is not required in neurons for action potentials in the axon since this only requires Na+ and K+ channels. c) does not impact the membrane transport of glucose in intestinal epithelial cell. d) does not require ATP to establish and sustain. e) is established entirely (only) by the Na+/K+ ATPase since it transports 3 Na+ out of the cell and 2 K+ into the cell for every cycle (ATP consumed).

Which of the following statements on membrane transport is NOT correct: A. To transport solutes in the unfavorable direction across the membrane, pumps couple the process with either ATP hydrolysis, light absorption, electron transport, or other favorable transport processes. B. Dissolved gases like O2, CO2, or NO simply diffuse across a membrane bilayer. C. Hydrophilic molecules require assistance by membrane proteins to cross the membrane bilayer. D. The rate of transport facilitated by transporters is faster but less selective for solutes compared to channels. E. The movement across the membrane that is facilitated by channels and transporters is always in the direction favorable for transport (i.e., ΔGt < 0).

Which of the following statements about transport through the plasma membrane of a cell is correct? (a) Both passive and active transport require the input of energy. (b) Passive transport does not require the input of energy, and active transport does. (c) Passive transport does require the input of energy, and active transport does not. (d) Neither active nor passive transport requires the input of energy.
Which statements are consistent with the known facts about membrane transport? (a) Active transport moves a substance from a region in which its concentration is lower to one in which its concentration is higher. (b) Transport does not involve any pores or channels in membranes. (c) Transport proteins may be involved in bringing substances into cells.
