- A research student creates an artificial animal cell containing a 5M solution of glucose with a selectively permeable membrane that only allows water to cross it. She places the cell into a beaker of water. After an hour, what effect do you expect to observe? (a) Water moves out of the cell causing it to shrink. (b) Glucose moves out of the cell until equilibrium is reached. (c) Water moves into the cell causing it to lyse/burst. (d) Glucose moves into the cell by facilitated diffusion. (e) There is no net movement of water or glucose. Explain your answerarrow_forwardIn cotransport (indirect active transport) (a) a uniporter moves a solute across a membrane against its concentration gradient (b) the movement of one solute down its concentration gradient provides energy for transport ofsome other solute up its concentration gradient (c) a channel protein moves ions by facilitated diffusion (d) osmosis powers the movement of ions against their concentration gradient (e) sodium is directly transported in one direction, and potassium is indirectly transported in the same directionarrow_forwardMatch each membrane molecule with its corresponding description.
