Michael Miller Biology 1208 Section 19 11-27-07 Conclusion Prior to the experiment, my prediction was that large heavy glycols would take longer to undergo hemolysis versus smaller, lighter glycols. My prediction turned out to be correct, and I therefore accept my alternative hypothesis. There was not much difference in the three trial runs for each solution, so I believe that my results are reliable and accurate. These results clearly agree with the fact that larger molecules are more impermeable to cell membranes than smaller ones. The results of the three glycols hemolysis times were all very linear in proportion to one another, and showed no immediate increase in time due to the weight of the glycol. This basically tells us that most particles of the same family will show similar results in relation to

Unformatted text preview: membrane permeability. Another step that could be added to this experiment would be to find out the charges of the molecules being tested, and determine if their electronegativity has any effect on hemolysis time. This could further enhance our understanding of the factors that determine membrane permeability, and could also disprove my hypothesis that just because a molecule is smaller it will pass through a cell membrane faster than a larger solution. Another experiment that could be conducted to further support my results would be to take the same glycols with the same concentrations as my experiment, and test their hemolysis time with a different type of blood cell....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
