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

Enzyme Reaction to Variable Elizabeth Alvidrez University of Texas at El Paso Abstract: An enzyme is a protein that serves as a biological catalyst (Denniston‚ 2007). Metabolic reactions happen with in cells. Enzymes are proteins that are used to speed up these reactions without being consumed by them (Mader‚ 2010). Catalase is a catalyst that digests potent hydrogen peroxide and converts it into H2O and O (Campbell Reese‚ 2008). The environment plays an important role

Concentration The Problem In many colleges over 8% of the students report problems concentrating on their studies. Most of these students blame outside distractions for their problems. Many research studies manipulating noise levels and distractions have found that such disturbances may increase‚ decrease‚ or not even affect concentration. These researchers have therefore concluded that distracters don’t cause concentration problems directly. It is the way the distracters are interpreted

Enzymes- reduce the amount of energy required for the reactions they catalyse [accelerate]. -thus‚ increasing the rate of reactions that occur in living organisms. WITHOUT enzymes : metabolism would be so slow at body temp. that insufficient energy would be available to sustain life. -Many enzymes are “Intracellular”- used within the cell that produced them e.g. enzymes in respiration & photosynthesis -Others are “extracellular”-they act outside the

ENZYME STRUCTURE AND FUNCTIONS: Enzymes are biological catalysts. 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 Definition of enzyme: A protein with catalytic properties due to its power of specific activation is defined as an enzyme. STRUCTURE Enzymes are proteins their function depends on its complexity. The reaction takes place in a small part of the enzyme

Introduction Over the course of several weeks‚ myself and my fellow classmates have been researching and conducting an experiment that focuses on the effect of ascorbate peroxidase (a.p) as well as salt stress at different levels of concentrations on Abelmoschus esculentus (okra). Okra is a plant that is composed of 87.1% of water. In addition to being made mostly of water this highly nutritious vegetable is also composed of 0.2% of fat‚ 9.7% of carbohydrate‚ 2.2 % protein‚ 1.0 % fiber‚ and 0

What happens? For many reactions involving liquids or gases‚ increasing the concentration of the reactants increases the rate of reaction. In a few cases‚ increasing the concentration of one of the reactants may have little noticeable effect of the rate. These cases are discussed and explained further down this page. Don’t assume that if you double the concentration of one of the reactants that you will double the rate of the reaction. It may happen like that‚ but the relationship may well

The Effect of Increasing Temperatures on the Enzyme Catalase Enzymes are proteins that help speed up chemical reactions inside your body and without enzymes‚ chemicals reactions in cells would be incredibly slow to a point where no activity at all takes place (Brawo press Inc‚ 2017). Enzymes speed up the chemical reactions by lowering the activations energy and they do this by binding substrates together in the correct orientation to react (Ernest Z‚ 2014). They are vital for life and serve a

affect Enzyme Catalysis Reaction Rates Introduction Molecules are constantly moving in our bodies and in nature. When molecules move fast enough they collide into one another‚ allowing chemical reactions to occur. Factors such as temperature and concentrations can either help increase or decrease these reactions. (Jubenville.) Enzymes are known as catalyst because they are able to speed up reaction rates without being destroyed or altered. They are able to encourage chemical reactions by decreasing
