Principles of Biology Lab Exercise Enzymes: Catalysts of Life Instructor: Professor Alcendor By Shahid Rana Date: March 7th‚ 2013 Abstract: In this experiment we have demonstrated the function of enzymes. The whole experiment was devoted to understand how enzymes work as a catalysts and increase the chemical reaction without being used themselves. In general‚ enzymes are proteins that function as biological catalysts. These enzymes adhere to lower to amount of energy required for

Enzymes Abstract: The following 2 labs experimented the more enzymes and substrates added to the concentration will effect the reaction rate. Our second lab‚ we tested enzyme and substrate concentrations to determine the increase of temperature and inhibitor. The enzyme source used in both labs was peroxide‚ guaiacol is used as a substrate for peroxide. We used Guaiacol‚ turnip extract‚ peroxide and distilled water for enzyme and substrate concentration. In the second lab we used the same substances

The enzyme tyrosinase was successively extracted by combining a homogenate of a potato and sodium sulfate with ammonium sulfate. Tyrosinase was successfully extracted by taking advantage of solubility properties of certain proteins. A standard curve was generated indicating dopachrome absorbance values through the use of a spectrophotometer and a computer graphing program. A spectrophotometer was used to measure either the amount of light that passed through a solution (transmittance) of the amount

Emission Spectroscopy Lab Introduction: According to the Bohr atomic model‚ electrons orbit the nucleus in fixed paths with specific energies. Each path is therefore often referred to as an “energy level”. Electrons possessing the lowest energy are found in the levels closest to the nucleus. Electrons of higher energy are located in progressively more distant energy levels. If an electron absorbs sufficient energy to bridge the “gap” between energy levels‚ the electron may jump to a higher

Biology 1 Cellular Processes Lab Section 903 Tianna Clarke Materials and Methods Part I – Restriction Enzyme Digestion To begin this experiment‚ the DNA molecules must be cut into smaller fragments with distinct enzymes called Restriction Enzymes through a process called Restriction Enzyme Digestion. Four microtest tubes were labeled 1 through 4 and added 10 µl of Enzyme Reaction Buffer to each of the four reaction tubes using a micropipette. DNA‚ and Enzyme 1 and 2‚ were then added to the reaction

Solvent/Water Trap Diagram Rodney Atwaters Halle Bair May 28‚ 2013 Chemistry 36100 Introduction The purpose of this lab was to produce benzoic acid by mixing sodium benzoate with hydrochloric acid. The Hydrochloric acid used in the experiment was a stock solution made by mixing HCl Acid and deionized water. HCl acid‚ historically called‚ muriatic acid or spirits of salt‚ hydrochloric acid is produced from sulfuric acid and common salt‚ NaCl (Princeton.edu). Since the early 1900 ’s‚ sodium
