Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution, slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide, a powerful and potentially…

The Effects of Enzyme Concentration on the Activity of Amylase To investigate the effect of Amylase concentration on its activity. the relative activity of Amylase is found by noting the time taken for the starch substrate to be broken down, that is, when it is no longer gives a blue-black colour when tested with iodine solution. This time is referred to as the achromatic point. Equipment: v Amylase solution 0.1% v Starch Solution 1.0% v Distilled water…

Title: “The Effect of Substrate Concentration, Enzyme Concentration, pH and Temperature on Enzyme Activity” Abstract: In the following experiments we will measure precise amounts of potato extract as well as Phenylthiourea, combined with or without deionized water and in some instances change the temperature and observe and record the reaction. We will also investigate the different levels of prepared pH on varying samples of the potato extract and the Phenylthiourea and record the results.…

Investigating the effect of temperature on the action of a protease enzyme on exposed developed film Plan Aim: The aim of the experiment is to find out what effect temperature has on the action of a protease enzyme on exposed developed film. Enzymes are biological catalysts. They are made in livings things built up by amino acids to make protein. Enzymes are able to speed up reactions and can repeat reactions. There are various factors that affect the activity of enzymes they are: "Y Temperature…

Abstract Enzymes are molecules that act as catalysts in the regulation of chemical and biological reactions in humans and other species. Every organ in humans depends on enzymes, as they are essential for optimal health. Most enzymes are protein molecules, which increase the reaction rate and function best under optimal conditions or temperatures related to the environment and the host organism where the enzyme is found. In this experiment, the digestive enzyme amylase was used in order to…

Assessment for DCP and CE Determining if temperature affects enzyme activity This investigation is using a range of temperature in order to find weather or not Temperature affects enzyme activity. I will: 1. Observe the effects of different temperatures on enzyme activity 2. Infer the relationship between the two 3. Use a line graph to display data and draw a conclusion Research Question How does temperature affect enzymes activity? Variables Independent Variable: Temperature Dependent…

Concentration on the Rate of Activity of the Enzyme Catalase Background Information: Enzymes are biological catalysts that increase the speed of chemical reactions without undergoing any physical change. They are neither used up in the reaction nor do they appear as reaction products. All enzyme catalysed reactions are reversible. Enzymes effectively lower the amount of activation energy required for chemical reactions to start. Some enzymes weaken covalent bonds within…

Enzymes are important to cells because they allow both the making and the breaking up of bonds. This would happen naturally and over time, but cells do not have the time to wait years, sometimes hundreds, for that to happen. With the use of enzymes, such tasks can take less than a second. This happens because enzymes are catalysts, and are able to speed up reactions. Enzymes, remaining unaffected by the process of catalysis, can continue to perform their function multiple times. However, like most…

Aim To investigate the effects of pH on enzyme activity Research question To what will pH levels 1,7,12 affect the rate at which liver catalase catalyzes the decomposition of 10ml of hydrogen peroxide (H2O2) to water (H2O) and oxygen (O2) exemplified by the volume of foam reached in 1 minute Hypothesis Since the optimum pH of liver catalase is approximately 7. I expect the greatest volume of foam to be achieved at pH of 7 because it is the optimum pH of liver catalase. I…
