The salt content within the cytosol of marine mammals is lower than the water that they consume from their environment. To maintain their salt concentration relative to their en- vironment, marine mammals rely on reticulate kidneys that have multiple lobes and allow for salt to be collected and excreted. How does the higher surface area of reticulate kidneys help marine mammals maintain their cellular salt-water concentration? A The higher surface area allows for a higher concentration of protein channels through which the salt can be actively transported. B C The higher surface area increases the volume of the kidney cells and allows for more ef- ficient transport of the salt across them. The higher surface area reduces the amount of ATP that is required for the removal of salt by allowing the salt to be removed via facilitated diffusion.

Vacuoles are fluid-filled organellespresent in some cells.Which function isNOT normally performed by vacuoles?
A solution of water and dissolved ions is separated by a selectively permeable membrane that allows the passage of water but not small ions. The concentration of sodium is higher on one side of the membrane than onthe other side. However, there is no net movement of water across the membrane. How is this possible?
Ion transporters are “linked” together—not physi-cally, but as a consequence of their actions. For example,cells can raise their intracellular pH, when it becomes tooacidic, by exchanging external Na+ for internal H+, usinga Na+–H+ antiporter. The change in internal Na+ is thenredressed using the Na+-K+ pump.A. Can these two transporters, operating together,normalize both the H+ and the Na+ concentrations insidethe cell?B. Does the linked action of these two pumps causeimbalances in either the K+ concentration or the mem-brane potential? Why or why not?
The primary function of the kidney is to exchange molecules across a membrane between the blood and the urine. One type of kidney cell has a basic rectangular shape, except for a single surface, which is lined with tiny, finger-like projections that extend into the surrounding extracellular space. Which of the following best explains the advantage these projections provide the cell? The projections increase the selectivity of the membrane because the small size of the projections limits the number of transport proteins that can be embedded in the membrane. The projections increase the volume of the cell without affecting the surface area, which increases the metabolic needs of the cell. The projections increase the surface area–to-volume ratio of the cell, which allows for more efficient nutrient exchange with the environment. The projections increase the speed at which an individual molecule can move,…

Here is a chloride cell in the gill epithelium of a fish. For reference, NKA = Na+/K+ ATPaseNKCC = Na+/K+/Cl- cotransporter. (image 1) The same proteins have been identified in shark rectal gland, marine birds and reptiles (salt glands in nostrils), marine fishes (chloride cells in their gills) and mammals that transport salt in their kidneys. (image 2) When biologists were testing the mechanism of salt excretion in sharks, they used a chemical called ouabain to inhibit the Na+/K+ ATPase to see if there was an effect. Which result would you expect to see with ouabain treatment? A. A decrease in Cl- in the epithelial cells. B. An increase in ADP in the epithelial cells. C. An increase in K+ in the epithelial cells. D. A decrease in Na+ in the epithelial cells.

During an investigation on membrane transport, a researcher exposed bacterial cells to different concentrations of two different solutes: A and B. The rate of transport of each solute into cells isrepresented in the graphSolute ASolute BSolute ConcentrationWhich of the following best explains the greater rate of transport for solute A than for solute B at higher solute concentrations?A Solute A is being transported by simple diffusion, which does not rely on membrane proteins to control the rate of transportSolute A is being transported by active transport, which uses ATP and has higher rates of transport than passive transportSolute A is being transported by facilitated diffusion, which uses membrane proteins to increase the rate of transportRate of Transport
Glucose is transported across the cell membrane of intestinal cells.
