    Lab activity 1: Effect of temperature‚ concentration‚ and pressure on equilibrium Introduction Our ongoing discussion has been on systems at dynamic equilibrium: for a reversible reaction‚ the rate of the forward reaction is equal to the rate of the reverse reaction. What happens if equilibrium is disturbed? In this lab activity‚ we are going to examine the effect of changing reaction conditions on the position of equilibrium. Part I: Effect of temperature We will consider the equilibrium

    Introduction I am going to try and measure the rate of respiration in yeast and find out what factors affect the rate of respiration. I am going to change the concentration of the glucose solution and I’m going to measure the volume of gas produced during respiration in cm³. Yeast contains enzymes. Enzymes speed up a chemical reaction – they’re biological catalysts. Yeast can respire both aerobically and anaerobic; the anaerobic respiration of yeast is known as fermentation. The equation for

    Wan Ching Man 5C(21) Effects of temperature on the activity of lipase Aim: To investigate the effects of temperature on the activity of lipase enzyme on milk which contain fats or lipids. Introduction: Enzyme is a kind of biological catalyst that made up of protein. It can speed up the metabolic reactions on various kinds of substances. Like lipase can break down lipid into glycerol or fatty acids in milk. Since enzyme is made up of protein which easily affected by varies temperature. This

    Ah Seung Chong Molecular Biology CTW: Enzyme Kinetic Dr. Cruz 07/22/2010 Enzyme kinetics Introduction Enzymes are biological catalysts or assistants‚ without enzyme many of important processes of life could not happen. Most of enzymes are proteins that help speed up chemical reactions by lowering amount of activation energy needed for the reaction1. Enzymes are usually highly selective‚ only bind to specific substrate and convert it to product at a particular rate1. The rate of the reaction

    flask using a volumetric pipette. The volumetric flask was then filled to the mark with distilled water. The flask was covered with Parafilm and inverted to mix. The next part of the experiment was to determine the Vitamin C in a solution of known concentration. Observations of the Vitamin C sample and the amount found on the label was recorded. A tared piece of weighing paper was used to weigh 0.27 g of Vitamin C. The Vitamin C was then transferred to a clean 50 mL volumetric flask. The flask was filled

    Explain the use of enzymes in food production by means of examples. You must include the example of lactase. Enzymes are proteins that speed up the rate of chemical reactions (up to a million times) in living organisms. Acting as catalysts they are not consumed nor altered in the process of converting the specific set of reactants into specific products. In food production‚ enzymes are greatly appreciated by their accelerated effect in biochemical processes and are mostly used in what we
