Going down the concentration gradient
WebConcentration Gradient: A measurement of how much the concentration of a substance changes across a distance. Passive Transport: Substances cross the cell mem-brane without the cell providing energy. Diffusion: A substance moves through a membrane from an area of high concentration to an area of low concentration. WebMar 5, 2024 · Ion channelsallow the formation of a concentration gradient between the extracellular fluid and the cytosol. Ion channels are very specific, as they allow only certain ions through the cell membrane. …

The … WebThe combined gradient that affects an ion includes its concentration gradient and its electrical gradient. A positive ion, for example, might tend to diffuse into a new area, down its concentration gradient, but if it is diffusing into an area of net positive charge, its diffusion will be hampered by its electrical gradient.
WebTo move substances against a concentration or electrochemical gradient, the cell must use energy. This energy comes from ATP generated through the cell’s metabolism. Active transport mechanisms, or pumps, work against electrochemical gradients. Small substances constantly pass through plasma membranes.
