Review Sheet Exercise 1 Cell Transport Mechanisms and Permeability Activity 1: Simulating Dialysis (Simple Diffusion) • Describe two variables that affect the rate of diffusion: Two variables that affect the rate of diffusion are size and concentration gradient. The molecular size vs the MWCO size of the membrane can either increase‚ decrease‚ or prevent diffusion. The greater the concentration gradient the greater the diffusion rate due to molecules moving from areas of higher concentration

Three treatment groups were utilized: a Gatorade group‚ salt-loaded (access to 0.9 g/l00 ml NaCl) group‚ and a group who only had water. In this experiment the class was able to observe and analyze the changes

PHYSIO EX 1 Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. The temperature of the solutions and the difference in concentration of the ion or molecule between the sides of the membrane 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? Since the chemical formula for urea is (NH2)2CO and its molecular weight is about 60. It will not diffuse through the
