Osmosis is the net movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. The water will continue to move across the semipermeable membrane as the system attempts to reach equilibrium, where both solutions have the same concentration. Semipermeable membrane Pure HO NaCl(aq) HO- -HO Time HO HO There are three different ways a solution can be described in relation to a cell placed in the solution: isotonic, hypotonic, and hypertonic. Compared to a cell, an isotonic solution exerts the same osmoti pressure as the cellular fluids. In other words, it behaves as if it had the same solute concentration as the cell. A hypertonic solution behaves as if it had a higher solute concentration than the cell. A hypotonic solution behaves as if it had a lower solute concentration than the cell. If a cell is placed in an isotonic solution, nothing happens to the cell because water moves into the cell at the same rate that it moves out of the cell. If a cell is placed in a hypotonic solution, water will flow into the cell, causing it to swell (and possibly burst). If a cell is placed in a hypertonic solution, water will flow out of the cell, causing it to shrink. Consider the three scenarios below. In each, a semipermeable membrane separates two solutions in a similiar manner as illustrated above. Indicate which solution will increase in Consider the three scenarios below. In each, a semipermeable membrane separates two solutions in a similiar manner as illustrated above. Indicate which solution will increase in volume. Beaker 1: Solution with 1.4% (m/v) starch Solution with 7.62% (m/v) starch Beaker 2: Solution with 2.3 M NaCl O Solution with 1.7 M NaCl Beaker 3: Solution with 1.5 M glucose O Solution with 0.5 M glucose A semipermeable membrane separates two solutions in a similiar manner as illustrated above. One side of the membrane has a concentration of 0.001 Minsulin. What is the concentration of insulin that needs to be on the other side of the membrane if the solutions are isotonic?
