Lindsay Kramer James Deorio, Michael Baley 4/16/08 BMS 113-70 UNIT 5; pt 1 Our hypothesis in this experiment was that the amount of succinate will directly  affect the rate of aerobic respiration. Our independent variable for this experiment is the  amount of succinate we added to each test tube. This is because it is directly altered by  the experimenters. The dependent variable is the rate of aerobic respiration because it is  directly related with the amounts of succinate in each tube. The control variables are test  tubes one and four. In tube one it contains 0 mL of succinate, so there will be no aerobic  respiration. Likewise, test tube four has 0 mL of DCPIP, the enzyme; also because we  do not have an enzyme, there will be no reaction. In conclusion, we can see that our hypothesis was supported. The difference in

Unformatted text preview: each tube can be explained by its progression of percent transmittance. The first tube (control #1) gained 6%. The second tube (of 0.1mL of succinate) grained 11%, the third tube (of 0.3mL of succinate) gained 11.5% and lastly the fourth tube (control #2) gained 6.5%. Also, as you can see on our graph, the amounts of succinate do effect the amount of aerobic respiration.

    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.
