⚡ Does Active Transport Use ATP? Let’s Break It Down
Active transport moves molecules against their concentration gradient (from low → high concentration). Unlike passive transport (diffusion), this process needs energy — and ATP is the cell’s main energy currency.
ATP powers active transport to keep ion gradients, nutrient uptake, and cell volume control working properly. No ATP = no active transport. 🔋
✅ Yes — most forms of active transport directly or indirectly require ATP (adenosine triphosphate).
