    Introduction Enzymes are catalytic proteins. The purpose of a catalyst is to speed up metabolic reactions by lowering the free energy of activation or activation energy. Activation energy is known as the amount of energy needed to push the reactants over an energy barrier‚ so that the downhill part of the reaction can begin (Campbell 151). In an enzyme catalyzed reaction‚ the enzyme binds to its substrate‚ which is the reactant an enzyme acts on. In the reactions‚ the enzymes are very specific

    Enzymes are important components of life‚ facilitating reactions that are necessary for an organism to live. Enzymes can be very specific to what environment they function best in1. Numerous environmental impacts were tested for the enzyme peroxidase which catalyzes the decomposition of hydrogen peroxide. The basic decomposition reaction was carried out first without any environmental alterations. The hypothesis for this reaction was supported. The enzyme caused the amount of absorbance increase

    concentration of substrate‚ on the activity of the enzymes. By conducting these three separate experiments also‚ three graphs are able to be obtained where the trend of each factor affecting on the enzyme activity is shown and described clearly. II. Hypothesis Experiment 1 (Effect of Temperature): As the temperature increases‚ the height of the bubble will increase too‚ indicating a faster rate of reaction. Experiment 2 (Effect of pH): Enzymes are affected by changes in pH. Extremely high or

    Introduction Enzymes are key players in metabolism. A metabolism is the organic processes in a cell or an organism that are necessary for life. An enzyme affects the rate at which a reaction occurs when the activation energy is lowered. In this reaction the reactant is called the substrate which is that combine with enzymes molecules to form a temporary enzyme substrate complex. During this products are formed and the enzyme molecules released is unchanged. For the substrate complex to form the

    Enzymes are generally protein macromolecules that act as catalysts in metabolic reactions. A catalyst is a chemical agent that speeds up a reaction without being consumed by the reaction. Enzymes speed up metabolic reaction rates by lowering the activation energy barrier‚ which is the amount of energy initially needed to spark a reaction. It allows reactant molecules to absorb enough energy to break bonds and react without raising the temperature to an extreme. During this process the substrate

    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

    Lab #5-Enzymes NAME DATE LAB PERIOD Introduction Enzymes are proteins‚ though highly complex and diverse‚ they serve one basic function; to work as an organic catalyst. A catalyst‚ as defined by Merriam-Webster dictionary‚ is a substance that enables a chemical reaction to proceed at a usually faster rate ("Catalyst-Definition and more."). They function by reducing the activation energy‚ or energy required to start a reaction. The way enzymatic reaction works cannot be altered‚ but the

    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
