throughout my experiments, so that temperature would not have an effect on my results. This would help me obtain more reliable and accurate results. Also, I made sure that I was drawing the solution up in the pipette beforehand, so that I could put it into the cuvette at exactly 30 seconds. This would make my results more accurate, as the solution would be put into the cuvette at precisely 30 seconds and so time would not have an effect on my results. I also used separate pipettes to measure out the
A chemical reaction is the interaction of two or more chemicals that produces a new chemical compound, most reactions require an increase in temperature, pressure, surface area, concentration or the inclusion of a catalysts to speed up the rate of reaction. Chemical reactions can be found in everyday life, without many of us knowing. Either it be a soluble tablet in water, or photosynthesis in a plant. The prerequisites for a reaction are known as the 'Collision Theory '. As stated by M. Ferguson
Introduction: Enzymes defined as biological catalysts that speed the chemical reaction by reducing the activation energy (Biology Department, 2014). Enzymes play an important biological role in the cell, as it is important to keep the cell alive by speed up the reaction, which explains why in absence of enzyme some reactions need long time (Richard & Mark, 2001). Also, enzymes regulate organism intercellular function for example enzymes help to keep human body healthy by defend it from infection
TITLE: ENZYME CATALYSIS PURPOSE: Measure the effects of changes in catalase concentration, substrate concentration, and salinity on the reaction rates of an enzyme. RESEARCH COMPONENTS: What is being tested-what do you know about enzymes? PRELAB QUESTIONS: Explain how the structure of an enzyme is related to its function/activity. All enzymes are structured to react with unique substrates. and each enzyme has an active site where the substrate bonds to the enzyme. The active site of an enzyme
be observing a chemical reaction dealing with enzymes. You may ask, what are enzymes? Enzymes are proteins produced by living cells. For example, you have enzymes in your digestive system to help you break down food. Without enzymes, organisms will not be able to survive. Enzymes act as catalyst in biochemical reactions and catalyst speeds up the reaction by lowering the amount of activation energy. Activation energy is required for reactants to react into products. Although enzymes are essential
An Investigation on the rate of reaction of the enzyme Catalase on the substrate Hydrogen peroxide. Plan Aim: To investigate the rate of the effect of Catalase on hydrogen peroxide. Introduction This investigation will be carried out to investigate the rate of reaction of the enzyme catalase on the substrate hydrogen peroxide. Enzymes are biological catalysts, which speed up the rate of reaction without being used up during the reaction, which take place in living organisms. They do this by
The Effect of Different Substrate Concentrations on the Rate of Reaction My aim is to investigate what happens when concentration of Hydrogen Peroxide is changed and how it affects the rate of reaction when it is broken down by the enzyme catalase (H2O2 à 2H2O + O2) Scientific knowledge. Enzymes are biological catalysts, regulating the rate at which chemical reactions take place without the enzyme being altered in the process. Enzymes bind temporarily
investigate the effects of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills, the experiment was done in order to determine how the rate of reaction will be altered, whether it will increase, decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant, animal, and microbial cell. There are thousands of different enzyme can be found in any cell. Enzymes can be describe
concepts to find out the different chemical reactions that take place in the bodies of living organisms and the influence of various organic substances in these reactions. The reactions are influenced by various enzymatic actions that are very important in the body as they help in activities such as the breakdown of substances for assimilation in the body. This paper explains the various processes taking place in the body and the effect of enzymes on chemical reactions in the body. Background information
