  • Investigating the Activity of an Enzyme

    643 Words  | 3 Pages

    Investigating the Activity of an Enzyme Sucrose using the enzyme sucrase (invertase) can be broken down into Glucose and Fructose. The aim of this experiment was to find about the activity of enzymes through measuring the micromoles of sucrase expressed whilst the following reaction occurs:- SUCRASE [IMAGE]SUCROSE GLUCOSE + FRUCTOSE C12H2201 H20 C6H12O6 C6H12O6 The progress of this reaction was monitored using Dinitrosaylic Acid (DNS) as the reagent reacts with the

  • Investigating Enzyme Activity

    3981 Words  | 16 Pages

    Investigating Enzyme Activity Aim: To investigate how the concentration of hydrogen peroxide effects the rate of reaction of an enzyme (catalase) Variables: These factors could effect the rate of reaction on an enzyme: · pH · Concentration · Temperature · Surface Area pH - Enzymes function at different pH values. In neutral conditions the amount of oxygen gas given of in an enzyme-catalysed reaction will increase. An enzyme is affected by how much acid or alkali is

  • Enzyme Activity in the Catalase

    1803 Words  | 8 Pages

    The purpose of this experiment was to see if there would be enzyme activity that is in catalase, which is found in potatoes. How my partner and me did the experiment was very simple, we put the filter paper filled with catalase concentration in to five sets of hydrogen peroxide. We found that the more concentration of hydrogen peroxide there was the faster it would take for the filter paper to reach the top, and the lower to no concentration level of hydrogen peroxide was the slower it would go to

  • The Effect of Temperature on Enzyme Activity

    1496 Words  | 6 Pages

    The Effect of Temperature on Enzyme Activity Experiment: To investigate the effect of temperature on enzyme activity. The enzyme used will be catalyse. The enzyme catalyse: The enzyme catalyse is a biological enzyme. It is used to break down Hydrogen Peroxide, which is harmful. The reaction that occurs is: [IMAGE] Hydrogen peroxide Water + Oxygen The activity of the enzyme catalyse can therefore be measured by the amount of oxygen (in the form of froth) that is produced

  • The Effect of pH on Enzyme Activity

    602 Words  | 3 Pages

    The Effect of pH on Enzyme Activity pH is a measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration, the lower the pH. Most enzymes function efficiently over a narrow pH range. A change in pH above or below this range reduces the rate of enzyme reaction considerably. Changes in pH lead to the breaking of the ionic bonds that hold the tertiary structure of the enzyme in place. The enzyme begins to lose its functional shape, particularly the

  • The Effects of Enzyme Concentration on the Activity of Amylase

    986 Words  | 4 Pages

    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 v Iodine in potassium

  • Factors Affecting the Rate of Enzyme activity

    1678 Words  | 7 Pages

    Enzymes are efficient proteins which play a part in cellular metabolic processes. Enzymes have the ability to improve the rate of reactions among living organisms. (Phillips, 2009) Although they work as a part of the reaction, they do not go through lasting alterations and therefore remain unchanged by the end of the reaction. They can only alter the rate of reaction. (Royal Society of Chemistry) Enzyme activity was first studied in a test tube in 1833 by Payen and Persoz. Temperature, pH, enzyme

  • Investigating a Factor that Affects Enzyme Activity

    1409 Words  | 6 Pages

    that Affects Enzyme Activity Planning -------- Aim --- To investigate a factor which will affect the activity of catalase, whilst keeping all variables constant. Possible Independent Variables ------------------------------ Here are a number of possible independent variables that could be changed in the experiment: Independent variable Continuous/Discontinuous Easy to measure? Volume of substrate used Continuous Yes Type of enzyme Discontinuous

  • The Effect of pH on the Activity of the Enzyme Amylase

    1088 Words  | 5 Pages

    the Activity of the Enzyme Amylase Aim :- To find the effect of pH on the activity of the enzyme amylase. An enzyme is a type of protein found in all living cells. Enzymes act as biological catalysts, breaking down substrates without needing a high temperature, allowing all the chemical reactions of metabolism to take place, regulating the speed at which they progress, lowering the activation energy and providing a means of controlling individual biochemical pathways. Enzymes owe
