BIOL 240W: Biology: Function and Development of Organisms

In cell biology, the "driving ion" is a pivotal concept. It refers to ions moving from areas of high to low concentration, generating energy for various cellular transport processes. This gradient is crucial for nutrient uptake and waste elimination. Multiple processes involve a driving ion, including facilitated diffusion, symport transport, primary active transport pumps, and cotransport. Facilitated diffusion aids molecule movement along their gradient, while symport moves multiple substance
