Lactic Acid – your muscles ache because of the accumulation of lactic acid. 2. Alcohol Fermentation- ethanol is fancy word for alcohol. Alcohol fermentation is alcohol + CO2 O2 Aerobic * Respiration * Mitochondria * Matrix – Krebs Cycle – C6 – gives

Karmini Mondal Chemistry 245- 061 Biosynthesis of Ethanol from Sucrose Introduction: Ethanol can be created using two methods: acid catalysed hydration of ethylene and through fermentation of sucrose. The purpose of this experiment was to use fermentation to produce ethanol from commercial sucrose (store-bought sugar)‚ using fractional distillation of the fermented solution. The percent ethanol in the fermented solution was then calculated. Mechanism: Results: Mass of conical vial 10.36 g

Chloroplasts and Photosynthesis All animals and most microorganisms rely on the continual uptake of large amounts of organic compounds from their environment. These compounds are used to provide both the carbon skeletons for biosynthesis and the metabolic energy that drives cellular processes. It is believed that the first organisms on the primitive Earth had access to an abundance of the organic compounds produced by geochemical processes‚ but that most of these original compounds were used up billions

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

Increased production of CO2 is a result of increased temperatures acceleration of the rate of fermentation. Abstract: We have tested the affects of increased temperature above room temperature on the rate of fermentation of yeast. We had 6 flasks filled with 6mL DI water‚ 2mL Yeast suspension and 6mL glucose of which 3 were at 25°C and 3 were at 37°C. The flasks at 37°C had each mixture pre-heated at 37°C for 2 minutes before being combined and then added to the flask where it was put into the

How Carboxylic Acids and Alcohols React to Produce Esters: Esters and Ester Production: Esters are abundant and ever present‚ and are the chemical basis of almost all fatty acids and oils. Small esters are responsible for the aroma of fruits‚ perfumes and‚ by extension‚ wines and other alcohols. Esters are formed when a carboxylic acid and an alcohol chemically combine‚ losing a molecule of water in the process. Carboxylic acids are organic molecular compounds that form a homologous series

On the periodic table‚ oxygen is the 8th element. It is located in period 2 and group 16. Oxygen is classified into many things. For example‚ on the periodic table‚ oxygen is classified as a nonmetal gas with an atomic number of 8 and atomic weight of 15.9994. In addition‚ it has 6 valence electrons. The symbol of oxygen is O and oxygen has 8 protons‚ 8 neutrons‚ and 8 electrons. The electron configuration of oxygen is 1s2‚ 2s2‚ 2p4. Oxygen had been produced by several chemists prior to its discovery

Oxygen Oxygen and its compounds play a key role in many of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism‚ the means by which animals derive the energy needed to sustain life. Furthermore‚ oxygen is the most abundant element at the surface of the Earth. In combined form it is found in ores‚ earths‚ rocks‚ and gemstones‚ as well as in all living organisms. Oxygen is a gaseous chemical element in Group VA of the periodic
