biology enzymes essay

Introduction Specific enzymes made up of proteins are used in biology to speed up a chemical reaction of any kind. Since a spontaneous chemical reaction can occur without help from any outside energy it could potentially prolong the reaction to where it becomes almost unnoticeable since it can take years for it to happen. For this reason, enzymes take action as a catalyst that speed up the reaction rate without completely being absorbed (Campbell et al., 2010). Enzymes are a form of regulation

FACTORS THAT AFFECT ENZYME ACTIVITY INTRODUCTION Catalase is an enzyme found in mammalian tissues and catalyzes the reaction by which hydrogen peroxide (H2O2) is decomposed into oxygen (O2) and water (H2O).(4) Enzyme activity and efficiency is affected by the conditions that the reaction occurs in. Changes in conditions can result in altering of the enzyme’s three dimensional shape and affect the enzyme’s function.(1) The conditions that influence the activity of an enzyme include pH, temperature

Introduction Without enzymes the existence of life is questionable since all metabolic processes in the cell cannot occur at a faster rate enough to sustain life. All the essential biological reactions in living things depend on enzymes’ catalytic activity. Enzymes are usually proteins, though some Ribonucleic Acid (RNA) molecules act as enzymes too, that speed up the rate of biological reactions without being consumed by the reaction. (Reece,2016, p.83) For instance, the presence of enzymes in the conversion

How Enzymes work in the home and in industry essay This essay aims to explore the ways on how enzymes are used in home and in industry, and it aims to explain the advantages and disadvantages of using enzymes in the home and industry. An enzyme is a protein that is formed by the body that acts as a catalyst to cause a certain desired reaction. Enzymes are very specific. Each enzyme is designed to initiate a specific response with a specific result. Firstly, the AQA Science Biology textbook published

How Varying Enzyme Concentrations Affect Absorbance Over Time in Potato Homogenate Mixture Haille Armstrong November 17, 2015 Biology 155 Laboratory-Tuesdays 6pm Lab Partners: Kayla, Morel, Ryan Abstract Saturation of substrates was a phenomenon that was observed in Part II of the experiment. This was referenced from later in the discussion. When the enzyme activity from this experiment was compared to Enoch’s work, (Enoch) it was stated that he found that in certain liver cells

the presence of an enzyme in the reaction, this process speeds up considerably. A reaction that takes seven years to complete, now takes less than a second to finish (Berenbaum 154). With the help of these enzymes, chemical reactions are sped up to where they are able to help with the natural processes of the world. An enzyme is an organic molecule that catalyzes reactions and speeds them up, but is able to be

Enzymes and pH Concentration Abstract Enzymes are high molecular weight molecules and are proteins in nature. Enzymes work as catalysts in biochemical reactions in living organisms. Enzyme Catecholase is found on in plants, animals as well as fungi and is responsible for the darkening of different fruits. In most cases enzymatic activities are influenced by a number of factors, among them is temperature, PH, enzyme concentration as well as substrate concentration (Silverthorn, 2004). In this experiment

Report on Measuring the Rate of Conversion of Hydrogen Peroxide using Enzyme Catalysis In essence, the main objective was to use chemical titration to measure and then calculate the rate of conversion of hydrogen peroxide (H2O2) to water and oxygen by using the enzyme catalase. Other purposes of the lab were; to measure the effects of changes of temperature, pH, enzymes concentration, and substrate concentration on rates of an enzyme. The lab was also an opportunity to see a catalyzed reaction in a

Determining Optimal pH for Tyrosinase-Catechol Reaction Rates Department of Biology, Swarthmore College Abstract The environmental conditions in which an enzyme is in heavily influence the rate at which it catalyzes reactions. Tyrosinase is an enzyme common in animals and plants, and is responsible for the pigmentation of skin and browning in plants. We measured the enzymatic reaction rate of tyrosinase in pH of 4,6 and 8 by assaying catechol’s transformation into ortho-quinone and used a spectrometer
