CELL TRANSPORT REVIEW Read each of the following questions and record your answer on your whiteboard. When I coundown “3, 2, 1” hold up your whiteboard with the answer facing forward. Any team that has all correct answers will earn a point. The team with the most points at the end wins! Which of the following is a function of the cell membrane?
