A scientist designs an experiment in which the movement of polar molecules through a cell membrane is tested. He sets up the following two experiments
in order to collect data on cell membrane permeability. What question is the
scientist most likely trying to answer by conducting this experiment?
Experiment 1
Exporimont 2
polar molecules
polar molecules
lipid bilayer
lipid bilayer proteins
O A. Are polar molecules able to diffuse across a cell membrane at a
greater rate than proteins?
B. How do transport proteins affect the diffusion of polar molecules
across a cell membrane?
C. How do polar molecules diffuse across a cell membrane?
D. What role do polar molecules play in the diffusion of proteins
across a cell membrane?
