Would water molecules move faster when there is a high concentartion gradient or low concentartion gradient? I think basically this question is asking if water molecules will move faster using passive transport or active transport? since it involves water molecules wouldn't it be passive transport since osmosis is a type of passive transport? I'm confused
1) a) Draw arrows to indicate which direction Na+ vs K+ions will tend to move.(into vsout of the cell) b) What prevents these solutes from diffusing across the membrane at a significant rate? c)If the solutes were unable to move across the membrane, would the cell be considered hypertonic, hypotonic or isotonic? d) If the solutes were unable to move across the membrane, which way would water move?(inside the cell, outside the cell or no net movement) e) How did the cell establish the differential in the shown ion concentrations in the first place?
Given the following cell type and solutions, draw the cell, showing the net direction of osmosis (water flow) and say what state the cell will be in. Choose from the following terms to describe the state of the cell: Turgid, flaccid, plasmolyzed, crenulated (shriveled), lysed (burst), normal. An animal cell with an internal osmolarity of 0.32 M (total concentration of all the solutes in solution) that is placed in a solution of 0.32 M NaCl.
The fluidity of the plasma membrane increases with 1.Increase in unsaturated fatty acids in the membrane 2.Increase in saturated fatty acids in the membrane 3.Increase in glycolipid content in the membrane 4.Increase in phospholipid content in the membrane
Information: Osmotic pressure is the pressure that a solvent exerts against a semipermeable membrane, such as a cell membrane. The higher the solute concentration, the lower the osmotic pressure. Red blood cells have an osmotic pressure equal to that of a 0.90% (m/v) solution of sodium chloride and 5.0% (m/v) solution of dextrose. A solution that has a higher concentration that this is called hypertonic; one with a lower concentration is called hypotonic. Osmotic pressure is an important factor affecting cells. Osmoregulation is the homeostasis mechanism of an organism to reach balance in osmotic pressure.Hypertonicity is the presence of a solution that causes cells to shrink.Hypotonicity is the presence of a solution that causes cells to swell.Isotonicity is the presence of a solution that produces no change in cell volume.When a biological cell is in a hypotonic environment, the cell interior accumulates water, water flows across the cell membrane into the cell, causing it to…

Does sodium chloride dissociate before going through the membrane? I am wondering because in semipermeable membranes, sodium chloride should be able to pass through, but if it dissociates, then it would need a transport protein.
