Cellular Respiration and Fermentation: Experimenting With CO2 and Redox Reactions Julius Engel; Section 8 Abstract In this experiment‚ the subjects of study were fermentation‚ mitochondrial respiration‚ and redox reactions. In the first experiment‚ yeast was grown in various carbohydrate solutions at various temperatures. In the second experiment‚ succinate was added to various samples of a mitchondrial suspension‚ DPIP‚ and a buffer. Then after two blanks were used‚ the samples

SCH4U7-02 Monday‚ October 21‚ 2013 Designing an Experiment to Investigate Factors Affecting Rate of Reaction Introduction Hydrogen Peroxide (H2O2)‚ is the most simple peroxide and commonly used in several household items such as toothpaste or as an alternative to bleach. However hydrogen peroxide it is a very dangerous substance when accumulated in large amounts. If that situation occurs this substance must be decomposed. But how can we decompose this reaction? Well it decomposes by itself

product. This is different from respiration because respiration transforms chemical energy into energy usable by cells; in this case chemical energy is the source. Photosynthesis occurs in the chloroplasts‚ using the chlorophyll inside of the chloroplasts‚ while respiration occurs in the mitochondria. Photosynthesis produces oxygen as a by-product‚ while aerobic respiration requires oxygen to even work. Photosynthesis produces NADPH2 in its workings‚ while aerobic respiration produces NADH+. Photosynthesis

Cellular Respiration is part of the metabolism of organisms‚ it provides the energy for organisms’ basic life activity. The process of cellular respiration converts oxygen and water to glucose and carbon dioxide‚ and usually occurs inside of mitochondria. Thus the cellular respiration is closely related to the life of all organisms‚ especially the human. In a case study in cellular respiration‚ seven unrelated people died in five days‚ and the reason is unclear. However‚ all the victim had same

Design of a Polystyrene Plant for Differing Single-Pass Conversions November 25‚ 2013 Introduction Polystyrene is one of the most widely used plastics‚ with applications ranging from food packaging to appliances to manufacturing (Maier). On an industrial scale‚ polystyrene is derived from its monomer‚ styrene. This is achieved by free-radical polymerization of a solution of monomer‚ polymer‚ and initiator. This reaction is a multistep radical reaction that
