    the reaction. We then added KMnO4, drop by drop, to see how much hydrogen peroxide remained in the solution, which was our dependent variable. An enzyme is a catalyst, and it has two fundamental characteristics that it is known for. One of these things it that it can increase the rate of a chemical reaction without being changed or destroyed in the reaction. The second is that they don’t alter the chemical equilibrium between the reactants and the products while they speed up the reaction. …

    during chemical reactions. Energy is released in the formation of bonds and energy is also released when the bonds are broken, but in both energy is required to start the chemical reaction. This energy needed to start a chemical reaction, activation energy, comes from enzymes. Enzymes (almost always proteins) are organic catalysts that help speed up the rate of reactions and allow the reactants to get the most out of the energy available. They do this without changing the reaction. Without an…

    Aqueous-Minerals Reactions: Chemical reactions involving aqueous species and mineral species are heterogeneous and slower compared to aqueous species reactions, thus modeled as rate dependent chemical reactions. This means that when mineral species (N_m ) are not is equilibrium with the aqueous species, the minerals can either dissolve or precipitate. As shown in equation R11 of an example of calcite dissolution/precipitation, a mineral species (Calcite) is involved in a reaction with only…

    The Effect of Decreased Amounts of DOPA on the Production of Dopachrome Intro Enzymes are a catalyst, typically a protein, that affects the rate of a chemical reaction. They allow these complex reactions to occur at a low temperature with less energy usage. In enzyme-catalyzed reactions, a substrate, the substance to be acted upon, binds to the active site on an enzyme to form the product. The active site is the only part of the enzyme that reacts with the substrate. For the substrate to become…

    the action of enzymes to carry out the reactions of life. According to the text in Campbell Biology, enzymes are biological catalysts. These globular proteins speed the rate at which metabolic processes occur by lowering the activation energy or the energy barrier required to transform reactants to products. Each enzyme is specific, each containing active sites destined for a substrate. Substrates are the reactants or starting materials of chemical reactions. The binding of substrate to…

    The kinetics of the reaction between peroxomonosulphate with Lactic acid was studied in the presence of Mn(II) at alkaline pH. The reaction followed first order with respect to peroxomonosulphate. The rate of the reaction was studied under pseudo first order condition and found to increases with the [Mn(II)] and lactic acid. Thermodynamic parameters were calculated and reported. Based on the results a rate equation, kinetic scheme and a most probable mechanism has been predicted. Keywords: Alpha…

    Research Question: To compare the enthalpy change of reaction of 3 neutralization reactions by using 3 different acids of distinct pH. The same base of NaOH will be used in all three experiments. Introduction: Chemical reactions always have energy change. Energy in the form of heat, if liberated is known as exothermic and if absorbed in the reaction is known as endothermic. When a reaction carried out under standard condition at a of temperature 298K and 1 atm of pressure and 1 mole of water…

    The simple reaction between two substances (Mg and HCL) was performed to determine how different factors such as, temperature, and concentration effects the rate of reaction. There were noticeable differences while determining the effects of concentration of HCL on the rate of reaction. Increasing in the concentration of the HCL, bottom of the test tube became hotter; it’s an exothermic reaction because energy is being released during the reaction in the form of heat. Another, increasing in…

    changes the conformation of the enzyme and its active site, so the substrate is not able to bind. This prevents the enzyme from lowering the activation energy of the reaction, and the reaction rate is reduced. However, allosteric inhibitors are not the only molecules that bind to allosteric sites. Allosteric activators can increase reaction rates. They bind to an allosteric site which induces a conformational change that increases the affinity of the enzyme's active site for its substrate.…
