- Which of the following statements are correct? P. Plasma membrane is highly impermeable to all charged molecules Q. All membrane transport proteins so far known, are transmembrane multipass proteins R. Ionophores operate by shielding the charge of the transported ion so that it can penetrate the hydrophobic interior of the lipid bilayer. S. Na+-K+ ATPase exchanges equal numbers of Na+ and K+ ions in each pumping cycle P and Q R and S P and S Q and Rarrow_forwardAn artificial cell consisting of an aqueous solution enclosed by a selectively permeable membrane is immersed in a beaker containing a different solution. The membrane is permeable to water and to the simple sugars glucose and fructose but impermeable to the disaccharide sucrose. Draw solid arrows to indicate the net movement of solutes (glucose and fructose) into or out of the cell. b. Is the solution outside the cell isotonic, hypotonic, or hypertonic to the cell? c. Draw a dashed arrow to show the net movement of water, if any d. Will the artificial cell shrivel, swell, or stay the same?arrow_forwardThe tails of the phospholipids of the plasma membrane are composed of _____ and are _____? a. phosphate groups; hydrophobic b. fatty acid groups; hydrophilic c. phosphate groups; hydrophilic d. fatty acid groups; hydrophobicarrow_forward
- What direction is the sugar molecule (the blue hexagon) going to diffuse? a. Into the cytoplasm b. Into the extracellular fluid (i.e. the fluid outside the cell) c. The same number of sugar molecules will move into the cytoplasm and the extracellular fluid. d. No diffusion will occur - the membrane prevents all molecules from entering or exiting a cell.arrow_forwardThe interface formed between two hydrophobic molecules in the context of the aqueous environment of the cell cytoplasm is formed mostly through: A. Hydrogen bonds B. Covalent bonds C. Van der Waals interactions D. Ionic bonds E. None of the abovearrow_forwardAccording to the fluid-mosaic model of the plasma membrane, a.protein and phospholipids form a regular, repeating structure. b.the membrane is a rigid structure. c.phospholipids form a double layer, with the polar parts facing each other. d.proteins are free to move within a double layer of phospholipids.arrow_forward
- Membranes are effective barriers preventing the crossing of both polar and nonpolar molecules from one side to the other. Explain why it is difficult for any species to pass from one side of a membrane to the other, more specifically explain how membranes are able to keep polar molecules out of the cell, keep nonpolar molecules out of the cell and what region of the membrae the polar and nonpolar/ hydrophilic molecules will not like being assoicated with.arrow_forwardWhat variable(s) influence(s) whether a nonpolar molecule can move across a membrane by passive diffusion? a. The structure of the phospholipids bilayer b. The difference in concentration of the molecule across the membrane c. The presence of transport proteins in the membrane d. All of the choices are correct.arrow_forwardWould it be possible for small ions to passively diffuse (simple diffusion) across a selectively permeable membrane? Why? A Yes, because ions are highly non-polar in nature B Yes, because ions are highly polar in nature No, because it needs the aid of transport proteins to cross the membrane No, because not only transport proteins but also metabolic energy from ATP are needed to transport ions across the plasma membranearrow_forward
