    experiment on the significant in strength of the enzyme by using three different test tubes and measuring the amount of product they give off. To determine this we are going to test the amount of color absorbance by using a special tool to help us understand our results. We will see how our end results show the effect of the amount of concentration we apply to each test tube. The results would be shown by the support of two graphs. Introduction: Enzymes are highly important because of the significant

    the Effect of Temperature on Enzyme Activity Almost all chemical reactions that occur in living organisms are catalyzed by enzymes. Many factors in a cell’s environment affect the action of an enzyme. In this investigation‚ you will design an experiment to determine the effect of temperature on an enzyme-catalyzed reaction. You will complete an entire lab write-up using the CHS LAB REPORT FORMAT. Fundamental Question How does temperature affect the rate of an enzyme-catalyzed reaction? Materials

    in these reactions‚ resource‚ products and enzyme are three most mainly things. In all chemical reactions‚ there is a activation energy(EA) needed for them. However‚ if the rate of reactions are too low‚ they will not be able to sustain lives. In this case‚ they have enzyme as a protein catalyst. As reaction catalystsenzymes are proteins that adjust the process by initiating the reaction. In this case‚ there are also many elements that influence enzyme working rates. For example‚ most living things

    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

    Hypothesis: If pH is increased or decreased past the enzyme’s optimum pH‚ the number of products produced by the enzyme will decrease because the enzyme will become denatured. Variables: The Independent variable is the pH of the environment. The uncertainty of pH is ± 1. pH is a unitless value. The Dependent variable is the number of products produced. The uncertainty of this this measurement is ± 1 product. In order for this experiment to be controlled‚ many variable were identified and held constant

    BIOLOGY HSC NOTES MAINTAINING A BALANCE • Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates. Enzymes are protein molecules that allow the body to engage in chemical reactions‚ such as metabolism. There activities can be catalytic (being able to control the rate of either increasing/decreasing chemical reaction) Enzymes have a specific shape‚ and this shape must be intact‚ otherwise the effectiveness

    certain environmental factors affect the enzyme activity rate. For the first experiment‚ where we tested the increase in concentration of enzyme with the substrate‚ we found that higher concentration of enzyme increases the rate of reaction of the enzyme. This is because more enzyme molecules are present‚ which allow more substrate molecules to get into the active sites of the enzyme (Sattler W& Esterbauer H). When calculating the absorbance of different enzyme concentration‚ it was noticeable that

    Purpose: Restriction enzymes cut DNA at a certain palindromic sequence. Three samples of lamda DNA set up to be cut with restriction enzymes PstI‚ EcoRI‚ or HindDIII. There were also two more samples‚ one of these samples was not mixed with any restriction enzyme and the other was a marker‚ which used an enzyme which creates fragments with a known number of base pairs used to create a standard curve. All five samples were put through agarose gel electrophoresis in order to estimate the amount of
