REVIEW SHEET EXERCISE 1 Cell Transport Mechanisms and Permeability NAME: Courtney Boyd LAB TIME/DATE: Simple Diffusion 1. The following refer to Activity 1: Simulating Dialysis (Simple Diffusion). Which solute(s) were able to pass through the 20 MWCO membrane? None According to your results, which solute had the highest molecular weight? NaCl Which solute displayed the highest rate of diffusion through the 200 MWCO membrane? NaCl Using the data from Chart 1, explain the relationship between the rate of diffusion and the size of the solute. As the size of the solute increased, the rate of diffusion decreased. Facilitated Diffusion 2. The following refer to Activity 2: Simulating Facilitated Diffusion. Did any of the substances travel against their concentration gradient? Explain why or why not. Yes, glucose did travel against its concentration gradient since the rate increased gradually as its concentration and carrier proteins increased. However, if there was not an increase in the rate, then glucose would travel with its concentration gradient. Using your results from Chart 2, what was the fastest rate of facilitated diffusion recorded? .0038
