Sterling Hayden AP Biology Mrs. Proehl 24 November 2014 I. Title Effect of Differing pH‚ Temperature‚ and Enzyme Concentration on Catalase Reaction Rate II. Introduction Enzymes are used to increase the rate of specific reactions in the body. Catalase‚ a specific enzyme‚ speeds the breakdown of hydrogen peroxide‚ a toxic chemical produced by cells in the body‚ into water and oxygen (Cain and others‚ 2010). The oxygen can be observed as bubbles coming from the reaction site. Catalase is found in many living tissues of organisms

Enzymes are proteins or nucleic acids that catalyze reactions. They are able to speed up reactions by reducing the activation energy of a reaction. Each kind of enzyme has a specific shape that matches its substrate so it can bind to its active site. Enzymes convert their substrates into a product. Enzyme activity are affected by factors such as temperature‚ pH‚ and time. If an enzyme is exposed to extreme heat‚ it will become denatured‚ that is‚ to become deformed and lose its original shape which

What is potential energy? Stored energy that results from the position or shape of an object is called potential energy. 2B.What factors affect an object’s potential energy? The factors that affect an object’s gravitational potential energy are its height relative to some reference point‚ it’s mass‚ and the strength of the gravitational field it is in. 2C. What is the potential energy of a 50-kg pole vaulter when

Enzyme Catalysis Introduction: Enzymes are produced by living organisms as proteins. These enzymes perform as catalysts to bring about a chemical reaction. In fact‚ most reactions are catalyzed by enzymes during reactions in the cell or in the human body. A catalyst that enzymes pose ad are by definition substances that are capable of initiating or speeding up a chemical reaction. Catalyst are not a necessity during a chemical reaction‚ they are just used to speed up a chemical reaction. This event

Enzyme lab report. Introduction. An enzyme is a protein molecule that speeds up the rates of chemical reactions by many folds. They recognize‚ bind‚ and change specific reactants. They do not change thus can catalyze the same reaction again and again. Activation energy also known as an energy barrier is the amount of energy needed in order to begin a chemical reaction. Catecholase catalyzes the reaction rate of catechol oxidation. Catechol is found beneath the skin of many plants such

area‚ which means there is more change of light hitting a chloroplast. Light is a very important factor when it comes to the process of photosynthesis‚ without light the reaction cannot be carried out and no glucose can be made. Light intensity is one of the factors that affect the rate of photosynthesis and that is what our experiment is based on: Aim: In this experiment we shall investigate how the rate of photosynthesis (measured by the increased volume of oxygen) is affected by changes of light

INVESTIGATING FACTORS AFECTING THE RATE OF PHOTOSYNTHESIS! Testing Carbon Dioxide Done by: Krish S. AIM: is to plan and carry out an investigation on factors affecting the rate of photosynthesis. We are doing this by investigating the amount of bubbles produced by waterweed to show the rate of photosynthesis and the effects of carbon dioxide (CO2). HYPOTHESIS: I think that the rate of photosynthesis will increase as the rate of CO2 increases this can be seen by the bubbles produced from

Healthcare reimbursement is the amount the provider’s office will be paid for their services rendered to a patient. There are different factors that may affect the amount of reimbursement a provider’s office may receive‚ such as charting‚ scheduling‚ diagnosis coding‚ procedure coding‚ evaluation and management codes‚ and claims filing. One of the ways providers can maximize reimbursement is through charting. Making sure all actions throughout the visit is documents is very important in order to

Patrick McCrystal Enzymes: Natural Catalysts Enzymes are catalytic proteins‚ meaning they speed up chemical reactions without beingused up or altered permanently in the process. Although various enzymes use different methods‚all accomplish catalysis by lowering the activation energy for the reaction‚ thus allowing it tooccur more easily. Enzymes have very specific shapes (conformations). Part of the conformationis the active site of the enzyme‚ where the actual catalysis occurs. The specific molecule

Title: The Effect of Varying Amounts of Substrate and Enzyme on a Reaction Rate Abstract In living organisms‚ certain reactions must take place rapidly to assist life. This occurs because of enzymes‚ because all reactions would take place too slowly to sustain life (Jacklet‚ 237). Enzymes are large protein molecules that catalyze specific chemical reactions without being used up in the process. Each enzyme has a region on its surface‚ called the active site‚ which recognizes a specific
