how are diffusion osmosis and active transport similarities

Simple diffusion is the passive movement of solute from a high concentration to a lower concentration until the concentration of the solute is uniform throughout and reaches equilibrium. Simple diffusion and osmosis are in some ways similar. It is also true for supersaturated solutions which are more and more important owing to the spreading of the application of amorphous solid dispersions for drug bioavailability enhancement. If there are different solutions at the two sides of the membrane with different equilibrium solubility of the drug, the difference in the degree of saturation is the driving force of passive membrane transport. passive drug transport) the driving force of passive transport can not be simplified to the concentration gradient. Since diffusion moves materials from an area of higher concentration to an area of lower concentration, it is described as moving solutes 'down the concentration gradient' (compared with active transport, which often moves material from area of low concentration to area of higher concentration, and therefore referred to as moving the material 'against the concentration gradient'). The difference of concentration between the two areas is often termed as the concentration gradient, and diffusion will continue until this gradient has been eliminated. The being permeable to water allows to and fro movement of water molecules along the concentration gradient.Diffusion is the net movement of material from an area of high concentration to an area with lower concentration. Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.Ĥ): is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane. Here metabolic energy ATP is required.ģ) Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport. In diffusion there is no challenge involved as it is along the concentration gradient, but in movement of molecules occur against concentration gradient ie from lower to higher concentration.Ģ) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. It may or may not occur across a semi permeable membrane.
