Which of the following is CORRECTLY matched with its function?

Question

Carrier proteins are specifically designed to bind with a molecule or ion, which they then transport across the cell membrane, from one side to the other. This process requires energy and is mediated by conformational changes in the protein. Channel proteins, on the other hand, form a pore within the membrane that allows ions or molecules to pass through based on their size and charge without binding to the protein directly. Receptor proteins are typically found on the extracellular surface of the cell membrane and bind to specific ligands, which can then trigger a cellular response. Cell identity molecules, also known as cell adhesion molecules, facilitate communication, recognition, and attachment between cells, helping to maintain tissue structure and function. Peripheral proteins are typically found at the surface of the membrane and interact with the lipid bilayer or other proteins without penetrating the hydrophobic core.
