15.3: Membrane Transport with Selective Permeability

WebIf a channel protein exists and is open, the sodium ions will be pulled through the membrane. This movement is used to transport other substances that can attach themselves to the transport protein through the membrane. Many amino acids, as well as glucose, enter a cell this way.

WebTwo important factors are involved in the passage of solutes across a selectively permeable membrane: 1) whether the membrane is permeable to the solute, and 2) the concentration (or electrochemical*, if ionic) gradient Solutes move across membranes by diffusion: DOWN their concentration or electrochemical (if ionic) gradient. * an ... WebOsmosis can be defined as the passive movement of water from a higher concentration to a lower concentration through a semi permeable membrane. Tonicity is how capable is a solution to change the size of the cell that is placed in it. Based on this measure, osmosis is divided into three groups: hypotonic, isotonic and hypertonic.
