Physioex 9.0 Review Sheet Exercise 1 Cell Transport Mechanisms and Permeability Name: Jeffery Cook Lab Time/Date: 12pm 2/09/2015 Activity 1 Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. a. Two variables that affect the rate of diffusion are size and whether or not there is an electrical or concentration gradient. 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

Activity 1 1. Size and concentration of the solute 2. It was too large to pass‚ as predicted 3. I predicted that the glucose would diffuse since it is small enough but the albumin is much too large to pass through the membrane. The experiment produced this result. Activity 2 1. Neither way requires ATP but facilitated diffusion requires carrier protein molecules for diffusion to occur. 2. By increasing the number of carriers more glucose can pass at a time increasing the rate‚

Review Sheet Exercise 12 Serological Testing NAME Kali Rothfuss LAB DATE/TIME 6/22/11 Positive and Negative Controls 1. Why are there a number of washing steps in serological tests? The are a number of steps needed in order to remove any non specific binding that may have occurred. 2. Describe how you would know that you had a “false positive” result. What does this mean for the rest of your results? A positive result with a negative control indicates a “false positive”

of water in the fluid that line the walls of the alveoli. Activity 5: Effect of Thoracic Cavity Puncture 1. What happened to the left lung when you clicked on the valve button? It deflated. 2. Why? Because the pressure in the left lung was 0 and the right lung changed rapidly‚ the air moved into the intrapleural space through the opening‚ causing intrapleural pressure. 3. What has happened to the “Total Flow” rate? It was reduced by ½. 4.
