Michael Miller Biology Lab 1208 Section 19 11-27-07 Introduction In this lab we explore the movements of molecules across cell membranes, and the time it takes to do so. During the activity, we will be studying the hemolysis rate of red blood cells. Hemolysis is the rupturing of red blood cells that are placed in a hypotonic solution (Rubin, 2000). On the other hand when a cell is placed in a hypertonic solution will shrivel and eventually crenate. The interesting thing about hemolysis is that it can be used as a method to determine osmosis rate, because it is not proportional to the rate of osmosis across the cell membrane. In this study we will be determining the hemolysis rate of bowvine red blood cells when placed in three different glycol solutions – ethylene, diethylene, and triethylene. These three glycols are excellent

Unformatted text preview: choices for this experiment because they provide a hypotonic solution for the blood cells to be placed in. Once the blood cells rupture, they excrete hemoglobin into the solution causing it to clear (Vaughn, 2002). In this particular lab, we will be examining if size and shape of the glycols in the solution will have an effect on hemolysis rate. I personally predicted that larger heavier glycols in solution would cause the rate of hemolysis to be slowed as compared to smaller glycols in solution. It is a known fact that smaller molecules will pass through a cell membrane much more quickly and easier than larger molecules. I hypothesized that ethylene would take the shortest amount of time before hemolysis, triethylene would take the longest, leaving diethylene with the second longest time before hemolysis occurred....
