The yeast Saccromyces cerevisae was placed in two different sets of test tubes along with glucose and MgSO4 or NaF to test the effects of the MgSO4 and NaF on yeast cellular metabolism. A third set of test tubes was used as a control. The results show that there is not a significant difference between any of the three groups, but experimental error may have caused these findings.
Yeasts are unicellular members of the Kingdom Fungi that can ferment sugar and produce ethanol. This particular experiment deals with Saccharomyces cerevisttae, a type of yeast that reproduces asexually by budding (Stanford). Yeast survives on oxygen, so it is an aerobe. It also has the amazing ability of adapting to oxygen-less environments and surviving as an anaerobe (Cofalec). Metabolism is the biochemical assimilation and dissimilation of nutrients by a cell (Munich). Redox reactions form new cellular material and generate energy. The different reactions can be divided into anabolism and catabolism (Gamboa).
