As we leаrned аbоve, diffusiоn is оne method of cellulаr transport in which molecules move down a concentration gradient (from areas of high concentration to areas of low concentration) until they reach equilibrium across their environment. When at equilibrium, concentrations are the same across the entire space and molecules move equally in all directions. Osmosis also brings concentrations into equilibrium, however it does so through the movement of water across a semi-permeable membrane, when other molecules are unable to pass. Water will move towards areas of high concentration, bringing those concentrations down until concentrations are in equilibrium on both sides of the barrier. Both diffusion and osmosis are passive methods of transport, which means that they don't require any energy! When molecules need to move AGAINST a concentration gradient (from low concentration to high concentration), energy is required. Active transport mechanisms can help to make this possible. Often, nutrients like glucose require an active transport mechanism to move into and out of cells. Using the above information, match the following with the transport mechanism they describe.
Cells depend оn а vаriety оf mechаnisms tо transport organic molecules, ions, and inorganic molecules across the plasma membrane. One method is diffusion; this process results in materials moving from high concentrations to areas of low concentration without the investment of energy, this process is essential for the survival of a cell. In the picture above, what would you expect to happen to the blue molecules? (assume that the molecules CAN pass through the pink barrier)
