Phenomena of active transport

Active transport is a process cells use to move molecules or ions across their membrane against their natural concentration gradient, meaning from low to high concentration. This requires energy, usually in the form of ATP, because it’s working against natural diffusion. Think of it like pushing a ball uphill, rather than letting it roll downhill. Cells use active transport to concentrate important substances, remove waste, or maintain balance (homeostasis), ensuring proper function and health. This process is essential for survival, enabling cells to regulate their internal environment effectively.
