Yоu аre studying hоw а mоlecule cаlled PA32 moves through the membrane of an animal cell. Through some measurements, you observe the following: PA32 is a large, polar molecule. PA32 can move through the membrane in either direction. PA32 always moves from a region of high concentration to a region of low concentration. No ATP is required for PA32 to move through a membrane. PA32 moves through a cell membrane with transport proteins but not through a synthetic membrane without transport proteins. Choose which phrases could accurately complete the following sentence. Based on the observations listed above, PA32 could pass through the membrane by ________. Select all that apply.
