Protein pumps are vital membrane proteins that facilitate the movement of specific ions or molecules across cell membranes, often against their concentration gradient. This energy-dependent process, known as active transport, is crucial for maintaining cellular homeostasis, nerve impulse transmission, and nutrient uptake. Key examples include the sodium-potassium pump, calcium pumps, and proton pumps, each playing a fundamental role in various physiological processes.
