Most materials entering the cell pass across the cell membrane by diffusion. In general, the larger the molecule, the slower the molecule diffuses across the membrane. The graph shows the sizes of several molecules that can diffuse across a lipid bilayer. Use the bar graph to answer the following question. Which of the following is a logical prediction based on the graph shown? Size of Molecules Carbon dioxide Glucose Oxygen Water 50 100 150 200 Size (daltons) Cells contain more glucose than oxygen O B Glucose molecules must not be able to cross the cell membrane Carbon dioxide crosses the cell membrane faster than glucose O D Glucose crosses the cell membrane faster than water Molecule
