Two simplified cell models are shown. Model 1: A cell boundary labeled cell membrane with inside shaded green. Arrows show oxygen (O) entering and carbon dioxide (C) leaving. A large particle labeled "protein chunk (P)" is blocked at the boundary. Model 2: Same cell and boundary, but now the arrow for protein chunk (P) crosses into the cell. Both models include the statement: "The membrane regulates exchange." What is the best prediction about what changed in Model 2?
