WebJun 20, 2024 · Carrier proteins known as uniporters bind to glucose molecules one at a time. The binding action causes a conformational change in the protein, which causes it to deposit the molecule on the opposite side of the cell. These carrier proteins operate without energy, and move molecules down their concentration gradient. WebCarrier proteins are proteins involved in the movement of ions, small molecules, or macromolecules, such as another protein, across a biological membrane. [1] Carrier proteins are integral membrane proteins; that is, they exist within and span the membrane across which they transport substances.
