Unformatted text preview: membrane. 2. Graphically represent simple diffusion, facilitated diffusion and active transport. 3. Regurgitate how biological systems move materials across membranes. III. Sample Problems: 1. Draw a graph predicting the relationship of simple diffusion across a membrane to temperature. Do the same for facilitated diffusion and active transport (use the range of O degrees to 80 degrees C.). 2. What determines the specificity of a membrane channel? 3. Which membrane would pass molecules through it faster assuming the same total number, not density of pores - one with a surface area of 2 mm^2 or one of 4 mm^2?...
