Protein Pump Moves ions and other solutes against the concentration gradient. In the primary active transport for transporting the molecules it uses chemical energy to push the molecule. Active Transport Definition Types Examples In 2021 Basic Anatomy And Physiology Study Biology Biology Facts Molecules required by the cell are specifically recognized by transmembrane proteins in the cell membrane. . Active transports are of two types. The real-time example for active transport is the sodium-potassium pump in the human body. In the secondary active transport proteins present in the cell membrane use the electromagnetic gradient to move across the membrane. These transmembrane proteins are powered by ATP. The cell membrane allows the passing of molecules of water and some small uncharged molecules such as oxygen and carbon dioxide. Endocytosis is a type of active transport that moves particles such as large molecules parts ...
