Effect of magnesium on Saccharomyces cerevisiae during cellular respiration Introduction All living things need energy to carry out the processes that occur during the life cycle. Energy is obtained by taking in some form of nutrient, whether it is ingested, or self produced during processes such as photosynthesis, and breaking it down into a usable chemical form known as ATP. Metabolism is a process that controls all of the chemically regulated reactions within living things, including the breaking down and building up of nutrients. Metabolism can take place in the presence of oxygen as aerobic respiration, or without the presence of oxygen as anaerobic respiration. My experiment examines the anaerobic respiration of Saccharomyces cerevisiae , known as fermentation. Fermentation is the breakdown of glucose into carbon dioxide, ethyl alcohol, and energy in the form of ATP. In an attempt to disprove my null hypothesis of magnesium not having an effect on CO2 production during cellular respiration of S .cerevisiae the object of this experiment was to test how magnesium affects the rate of fermentation in S.

    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.
