Introduction “The Enzyme Reaction” An enzyme is a protein that acts as a catalyst‚ which brings out a biochemical reaction. A Catalase enzyme‚ the enzyme tested in this experiment‚ is found in almost all living organisms that are exposed daily to oxygen (such as fruits‚ vegetables and animals). Background Information The Catalase enzyme in this experiment is known for being less affective the warmer the temperature is. According to “Science fair projects” an enzyme becomes unstable

Reaction of Enzyme Amylase Research Question: How will changing the percentage of sodium chloride concentration affect the rate of reaction of enzyme amylase‚ measured using the absorbance of starch and iodine with a spectrophotometer. Introduction: Amylase is an enzyme that is involved in the human digestive process. Found in both the human pancreas and the human saliva‚ amylase breaks down starch into sugar so that large molecules can be easily digested1. Like all enzymes‚ amylase must be kept

aim of this 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

Experiment 2: Starch Hydrolysis by Amylase Theoretical Background Polymers of carbohydrates are called polysaccharides‚ and make up some of the most important naturally occurring compounds [1]. They have thousands of monosaccharide units linked to each other by oxygen bridges. They include starch‚ glycogen‚ and cellulose‚ all three of which yield only glucose when completely hydrolyzed [2].

Core Practical: Enzyme concentrations and enzyme activity. Introduction In this experiment I shall investigate how the enzyme concentration can affect the initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis

affecting Enzyme Activity: The effect of pH on enzyme activity Background Knowledge: An enzyme is a biological catalyst – which speeds up the reaction rate‚ without itself getting altered. Enzymes are proteins with long polypeptide chains that are folded up into three – dimensional shapes. An enzyme acts on a substrate to convert the substrate into a product useful for the organism.The active site is a special region on the surface of the enzyme where the substrate binds to the enzyme.

THE EFFECT OF TEMPERATURE ON CATALASE ACTIVITY AIM The aim of this experiment is to find out the effect of temperature on catalase or hydrogen peroxide. This will enable us to tell at what temperature hydrogen peroxide is most efficient. This (degradation) reaction will help us determine some of the catalase’s different attributes. HYPOTHESIS In this experiment it would be safe to hypothesise that no activity would take place at 1 to 20 degrees. It would be probable that a little activity would

Usman Omid Biology IB 1A The Effect of Temperature on Beetroot Membranes _Aim_ This practical will test the effect of temperature on the integrity of the membranes‚ _Introduction_ The cells of beetroot contain a pigment called betalain in their vacuoles. It is kept inside the cells by the membranes. If these membranes are damaged‚ then the betalain leaks out. The amount that leaks out can be assessed‚ as the leaked out pigment will color the water surrounding the cells. This information can

catalyst is called biological catalyst‚ and enzyme is an example of biological catalyst. Enzyme is very important for biochemical reactions‚ as it helps the reaction to become faster than usual. The reactions with enzymes will react 10 billion times faster than those solutions without enzymes. (clitoncc)The enzymes can only react with one particular reaction‚ in order for the reaction to react it needed to find the correct enzyme.

Background Information Part 1 In the first part of the enzyme lab‚ we mixed a substrate and an indicator with an enzyme. There was also a neutral buffer in each of the chemical mixtures. The neutral buffer regulated the pH to around 7. We got a color palette and once we mixed each together‚ we observed and saw a change in the color of the substance. The darker and more brown the substance got‚ the more oxygen produced by the reaction. Our results showed that amount of oxygen produced increased
