How a cell uses active transport

WebActive transport: the sodium-potassium pump. Since the plasma membrane of the neuron is highly permeable to K + and slightly permeable to Na +, and since neither of these ions is in a state of equilibrium (Na + being at higher concentration outside the cell than inside and K + at higher concentration inside the cell), then a natural occurrence should … WebActive transport mechanisms require the cell’s energy, usually in the form of adenosine triphosphate (ATP). If a substance must move into the cell against its concentration gradient—that is, if the substance's concentration inside the cell is greater than its concentration in the extracellular fluid (and vice versa)—the cell must use energy to …
