How do carrier proteins change shape
WebCarrier proteins change shape as they move molecules across the membrane. (Attribution: Mariana Ruiz Villareal, modified.) Carrier proteins play an important role in the function of kidneys. Glucose, water, salts, ions, and amino acids needed by the body are filtered in one part of the kidney. 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.
