Osmosis, Active Transport and Absorption 0.0 / 5 ? BiologyCellular processes and structureASAQA Created by: Ellie RiversCreated on: 11-05-13 12:21 Osmosis the passage of water from an area of high water potential to an area of low water potential across a partially permeable membrane 1 of 5 Isotonic solutions that possess the same concentration of solutes so therefore have the same water potential, leading to no osmotic movement 2 of 5 Active Transport the movement of molecules from an area of low concentration to an area of high concentration against the concentration gradient using ATP 3 of 5 Absorption and Diffusion absorption of glucose in the blood and villi helps maintain a constant concentration gradient to allow diffusion to continue 4 of 5 Absorption and Active Transport glucose is absorbed with sodium through the sodium-potassium pump up their concentration gradient 5 of 5
