The model shows two types of proteins, channels and carriers, allowing the movement of molecules into the cell. As indicated by the model, what question is best asked about the role of the proteins in this type of transport? A) How can proteins be used in active transport? B) How do proteins allow for endocytosis of large molecules? C) How can molecules move against the gradient through proteins? D) How do proteins allow for facilitated diffusion of molecules into the cell?
