How do carrier proteins change shape
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. WebDec 24, 2024 · Carrier proteins change shape as they move molecules across the membrane. An example of this process occurs in the kidney. Glucose, water, salts, ions, and amino acids needed by the body are filtered in one part of the kidney. This filtrate, which includes glucose, is then reabsorbed in another part of the kidney.
