Active Transport Pumps |link| Jun 2026

Active transport pumps are integral membrane proteins that move ions or molecules across a biological membrane against their electrochemical gradient (from low to high concentration). This process requires an external energy source, typically adenosine triphosphate (ATP), light, or electron flow. These pumps are essential for maintaining cellular homeostasis, nerve impulse transmission, nutrient uptake, and waste removal.
