Active Transport Protein < FHD 1080p >

In biology, this "against the flow" movement is called , and it’s made possible by tiny, mighty molecular machines: active transport proteins . What Are Active Transport Proteins? Unlike channel proteins that simply open a door for molecules to fall through (diffusion), active transport proteins are bouncers with attitude . They grab specific molecules and physically pump them across the cell membrane—from low concentration to high concentration.

So the next time you take a deep breath (oxygen enters passively) but digest a meal (glucose enters actively), thank the tiny, energy-burning bouncers inside your cells. Read about ABC transporters—a huge family of active transport proteins involved in cholesterol transport, drug resistance in cancer cells, and even eye health. They grab specific molecules and physically pump them
