Investigating Enzyme Activity Essay

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…

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…

Effect of pH on Enzyme Activity Biology 1630 By: Princetta Samuels November 30, 2015 Abstract: The experiment was to assay and study an enzyme called peroxidase using a spectrophotometer. Determining the effects of pH on peroxidase is one of the main actions of this specific experiment. Investigating the special effects of several pH solutions and analyze the color alteration and then equating the absorbance in their outcomes by graphing pH levels within seconds. Introduction: Enzymes are particular…

Borad The Effect of pH on Enzyme Activity Introduction: Metabolism is a necessary process in the function of living cells, which is driven by enzymes. Enzymes are catalysts that speed up chemical reactions by lowering the activation energy. Changes in the pH of an environment in which the enzymes act affect their performance capability. The optimum pH is the pH in which the enzymes catalyze the reaction at the fastest rate. The type of enzyme affects its optimum pH. Enzymes are typically denatured…

The purpose of this experiment is to measure the rate of catalase enzyme activity under different temperature conditions. The catalase enzyme is to be experimented on 4 different temperatures of 0oC, 23oC, 37oC, and 55oC, to determine which temperature has the fastest and slowest rate of enzyme activity, Introduction All organisms are made of the basic unit of life called cells. From bacteria to fish to plants to humans, they are all supported by the cell theory. The cell theory “states that all…

temperatures affect the rate of enzyme activity, with the enzyme catalase. Introduction This experiment is designed to test the role of temperature on enzyme activity. Enzymes are “molecules that function as biological catalysts” (Reece 2015). They act as catalysts by speeding up the rate of a chemical reaction by “lowering the activation energy needed for the reaction to begin” (Reece 2015). The enzyme being used in this experiment is catalase. Catalase is an enzyme that is found in nearly all living…

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…

Gautsch1 Lab 6: Enzymes John Gautsch September 24, 2014 Abstract Lab six requires students to observe the effects of pH and enzyme concentration on catecholase activity. Enzymes are organic catalysts that can affect the rate of a chemical reaction depending on the pH level and the concentration of the enzyme. As pH comes closer to a neutral pH the enzyme is at its greatest effectiveness. Also at the absorbance of a slope of 0.0122 the enzyme is affected greatly. The pH effect on enzymes can be tested…

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…

investigate how temperature affect enzyme activity. Background information: Enzymes are globular proteins (see figure 1) that can be found in all the living cells. They can be used as biological catalysts by lowering the energy that the chemical reaction requires to occur. Certain enzymes only catalyze certain biochemical reactions and this property is known as enzyme-substrate specificity. Living organisms can produce many different enzymes. In order to further explain enzyme-substrate specificity, a basic…
