WebFeb 17, 2024 · Carrier proteins carry the ions or molecules across the membrane by changing their shape after binding to the substrate. Though not clearly understood, carrier proteins are found to change shape when their hydrogen bonds get affected. This change in structure allows the bound molecule to move from one side of the cell to another. WebCarrier Proteins transport substances through the cell membranes against (active transport) or down the concentration gradient (facilitated diffusion). Moving substances against the concentration gradient requires energy. …
WebFor instance, in the figure below, a carrier protein lets sodium ions move down their gradient, but simultaneously brings a glucose molecule up its gradient and into the cell. The carrier protein uses the energy of the sodium gradient to drive the transport of glucose molecules.
