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 acts as the "battery" for the cell. When ATP is hydrolyzed (broken down into ADP + Phosphate), it releases energy. Membrane proteins capture this energy to change shape and physically pump molecules across the membrane. does active transport use atp
