THE EFFECT OF TEMPERATURE ON CATALASE RESEARCH QUESTION: What is the effect of various temperatures‚ 0°C‚ room temperature‚ 37°C‚ 50°C‚ 60°C‚ on the number of oxygen gas bubbles liberated‚ in a decomposition reaction between the enzyme Catalase‚ obtained from crushed mung beans‚ and 2% of the substrate Hydrogen Peroxide? INTRODUCTION: Enzymes are biological catalysts that increase the rate of chemical reactions without they themselves being involved in the reaction itself. Enzymes are proteins

experiment was to determine the effect of caffeine on resting body temperature. This has to do with homeostasis‚ which is the maintenance of equilibrium. In other words‚ it is a stable body state. Homeostasis refers to the process of keeping the internal body environment in a steady state‚ when the external environment is changed (Homeostasis 2). Humans are warm-blooded creatures that generate body heat internally and maintain body temperatures at a fairly constant level – about 98.6oF (Chiras 3). In this

phosphorylase in particular) are affected by varying its temperature before introducing it to the substrate it will be reacting with. A catalyst (enzyme) is a substance that changes the rate of a reaction; for a reaction to take place at all‚ the enzyme must first come into contact with the substrate. Enzymes are subject to a number of factors which effect how fast they can cause a reaction with a substrate; these factors include temperature‚ pH levels‚ chemical substances and the concentration of

Introduction The UK government set up High Speed 2 (HS2) Ltd in January 2009 to consider the case for new high speed rail line between London and Scotland capable of carrying passenger trains at speeds up to 250 miles per hour. The broad plan for the network to Manchester and Leeds including the section between London and the West Midlands is roughly the shape of a letter Y. The “Service specification assumptions for the Y network” shows a total of 18 trains per hour (tph). The government and its
