Abstract The purpose of this experiment is to test for mitochondrial activity by isolating different organelles using the differential centrifugation process. Studying mitochondria is extremely important because they control the death and life of the cell by regulating the apoptotic signals (Frezza et al 2007). Also they are responsible for the metabolic reactions (aerobic respiration) and the production of ATP (Frezza et al 2007). Three hypotheses were formed based on my knowledge.
The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.
