Introduction “The Enzyme Reaction” An enzyme is a protein that acts as a catalyst‚ which brings out a biochemical reaction. A Catalase enzyme‚ the enzyme tested in this experiment‚ is found in almost all living organisms that are exposed daily to oxygen (such as fruits‚ vegetables and animals). Background Information The Catalase enzyme in this experiment is known for being less affective the warmer the temperature is. According to “Science fair projects” an enzyme becomes unstable

Courtney Jablonowski Dr. Peterson Lab Report 1 June 17‚ 2012 Results The tooth formula is a shorthand technique that biologist use to keep track of the teeth on a particular jaw. The formula consisted of two lines‚ top jaw and bottom jaw‚ which were used to count how many incisors‚ canines‚ premolars‚ and molar teeth a species had. Species A‚ Odocoileus virginiaus (white-tailed deer)‚ had a tooth formula of 0033/3133. On the top jaw‚ the deer had zero incisor and canine teeth but have

In the film Up in the Air relationships are the topic. We are first introduced to the main character in the work place. His name is Ryan Bingham and his job is corporate downsizing. Ryan travels all over the country 320 days a year and fires people. Ryan lives a very isolated existence by choice‚ his second job as a motivational speaker is not very motivational at all. His message is one of removing emotional and access baggage. He feels he has everything under control until two women enter his life

interprets the data shown on the table of results. The graph shows that the highest rate of reaction is at pH 7. This therefore supports my theory that at pH 7 the rate of reaction will be highest. This relate to other resources‚ such as books and the internet‚ which show that the optimum pH value for catalase is pH7‚ therefore there is no difference between the optimum pH and the pH used in the experiment‚ hence the enzyme structure is not affected by the pH and is most active. However the graph inadequately

How to Write a Reaction Paper. In writing a good reaction paper‚ it is not enough to simply praise the strengths or criticize the weaknesses of the text in question. More than that‚ you must be able to justify your "reaction." It is important to provide the reasons why‚ for example‚ the first chapter of a novel is dragging‚ or why the thesis of a particular essay carries a strong point. Of equal significance is your ability to further support your reasons with academic theories or even statistical

Grade 12 Biology (SBI 4U1) Nicole Mikulis Unit: Biochemistry Sept 14 2012 Lab: Effect of temperature and pH on catalase activity BACKGROUND Catalase is an enzyme that detoxifies chemicals that might harm the cell such as hydrogen peroxide (H2O2). The enzyme breaks H2O2 into water and oxygen. The production of the oxygen gas bubbles serves as evidence that the catalase enzyme is working. As catalase is breaking the bonds between H2O2‚ it is releasing energy in

CHAPTER 4: ENZYMES Enzymes are biological catalysts. There are about 40‚000 different enzymes in human cells‚ each controlling a different chemical reaction. They increase the rate of reactions by a factor of between 106 to 1012 times‚ allowing the chemical reactions that make life possible to take place at normal temperatures. They were discovered in fermenting yeast in 1900 by Buchner‚ and the name enzyme means "in yeast". As well as catalysing all the metabolic reactions of cells (such as respiration

Transpiration Lab Write-up. Introduction Transpiration is the evaporation of water from plants. It’s not simply a hazard of plant life but it’s the engine that pulls water from the roots to cool the leaf and supply photosynthesis. The concentration of water vapor in the atmosphere is lower than that in the leaf. Because of this difference‚ water vapor diffuses from the spaces of the leaf‚ through the stomata in the epidermis. Stomata are in the lower epidermis; the lower surface receives less

Title: Enzyme Catalysis of Hydrogen Peroxide by Catalase Problem and Objectives: How do different temperatures and different levels of pH affect the reaction rate of the enzymes in chicken liver? Demonstrate the activity of an enzyme in living tissue‚ observe the effects of changes in temperature and pH on the activity of an enzyme‚ perform analyses for the presence of an enzyme in tissues‚ and analyzing relationships between environmental conditions and enzyme activity. Background: Cells produce

Starch is a type of Carbohydrate that’s made from thousands of glucose units. Simple sugars are the basic units that make up starch. Carbohydrates provide us with energy so that we can carry out our daily routines. Our body then digests it into glucose so we can have energy to do that. Saliva is a form of chemical digestion that is in the mouth. Amylase is an enzyme that catalysts the breakdown of starch into sugars. Amylase is present in human saliva‚ where it begins the chemical process of digestion
