Simulating Dialysis (Simple Diffusion)

1. Describe two variables that affect the rate of diffusion. ______________________________________________________ __________________________________________________________________________________________________ 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? ____________________________________________________________________________________ 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? ___________________________________________________________________ __________________________________________________________________________________________________ 4. Put the following in order from smallest to largest molecular weight: glucose, sodium chloride, albumin, and urea. ______ __________________________________________________________________________________________________ A C T I V I T Y

Simulated Facilitated Diffusion

1. Explain one way in which facilitated diffusion is the same as simple diffusion and one way in which it differs. __________ __________________________________________________________________________________________________ 2. The larger value obtained when more glucose carriers were present corresponds to an increase in the rate of glucose transport. Explain why the rate increased. How well did the results compare with your prediction? ___________________ __________________________________________________________________________________________________ 3. Explain your prediction for the effect NaϩClϪ might have on glucose transport. In other...
