- The contraction of cardiac muscle cells results from the increase in Ca?+ levels in the cytosol. For these cells to relax, an antiport removes Ca?+ from the cytosol for every Nat that is taken in. Digitalis is a drug that is used to make the heart contract more strongly. This drug partially inhibits the Na*-K* ATPase in the cardiac cells. Applying the concepts from membrane transport, answer the following: a. Propose an explanation for the drug's effect. b. What will likely happen if too much of the drug is taken in? Why do you say so?How do electroneutral co-transporters depend on the transmembrane potential? Select one: a. They depend on the transmembrane potential to some extent b. They are completely independent of the transmembrane potential c. They very slightly depend on the transmembrane potential d. They strongly depend on the transmembrane potentialABC transporters are: a. An example of active transport with activity in multi-drug resistance. b. An example of passive-mediated transport with activity in multi-drug resistance. c. An example of an ion channel that binds ATP for effective transport. d. An example of a pump involved in Ca2+ transport. e. An example of an antiporter.
- Here is a chloride cell in the gill epithelium of a fish. For reference, NKA = Na+/K+ ATPaseNKCC = Na+/K+/Cl- cotransporter. What type of fish would you expect to see this type of chloride cell? A. fresh water fish B. salt water fish C. eitherHere is a chloride cell in the gill epithelium of a fish. For reference, NKA = Na+/K+ ATPaseNKCC = Na+/K+/Cl- cotransporter. The NKCC (Na+ K+ Cl- cotransporter) moves Cl- into the cell against its concentration gradient. What type of transport does NKCC carry out?A. passive diffusionB. facilitated diffusionC. secondary active transportD. primary active transportHere is a chloride cell in the gill epithelium of a fish. For reference, NKA = Na+/K+ ATPaseNKCC = Na+/K+/Cl- cotransporter. CFTR allows for movement of Cl- from inside the cell out into the water down a concentration gradient. Which of the following would be true of CFTR? A. It is a primary active transporter. B. It is a symporter. C. It is a secondary active transporter. D. It is a channel that allows for facilitated diffusion.

- A 500mL beaker is equally divided by a membrane permeable only to NaCl. Side A contains 250mL of a 1x10-6M of NaCl. Side B contains 250mL 1x10-12M of NaCl. In which direction will the NaCl diffuse? Select one: a. Diffuse Side A to Side B. b. Diffuse Side B to Side A. c. No diffusion will occur; it is already at equilibrium.Which of the following statements about "leak channels" in the plasma mem- brane is correct? A. Proteins that form these channels bind to solutes to allow them to pass into the cell. B. They are passageways formed by proteins to allow water and ions to move passively through the membrane. C. They allow small ions and molecules to move between adjacent cells. D. They are formed by glycoprotein and proteoglycans to allow hormones to enter cells.Below are three statements - two of which are truths and one is a lie. Which of the following statements is a lie? Select one: a. Both primary and secondary transport moves solutes against their concentration gradients. b. The primary active transport prepares the conditions of the membrane gradient by making the extracellular membrane slightly more negative than the intracellular membrane. c. The primary active transport uses ATP while secondary active transport helps replenish ATP.
