  • Enzymes

    Schaffer Intro: Enzymes are important biological molecules that help catalyze numerous reactions in the body. They are an arrangement of proteins designed to serve very specific roles. Enzymes contain active sites that substrates bind to. The enzymes then help orient those substrates so they achieve ideal reaction conditions. As a result, substrates are broken down much faster than they would on their own (Lawless 2016). Due to the fact that so many different arrangements of proteins are possible, it’s no surprise that so many reactions in the body are all able to proceed faster with the help of enzymes. In this lab, catalase was used to break down hydrogen peroxide and measure the reaction rates depending on the H2O2 concentration. The purpose of this was to see if the concentration of H2O2 affected the rate of the reaction. The hypothesis tested was that larger substrate concentrations should result in…

  • Synthesis Of An Enzyme

    II. Introduction An enzyme is a specific type of macromolecule known as a catalyst, that accelerates the rate of chemical reactions by taking part in the reaction without being consumed (Wilson, et al 2015). Enzymes participate in these reactions inside the cell and decrease the activation energy required to begin the reaction. These catalytic agents bind to substrates that are changed into products. A component of the enzyme that is responsible for binding to substrate or the reactant is…

  • The Importance Of Enzymes

    Enzymes are found in all living organisms. They are present to speed up or accelerate a chemical reaction; referred to as a catalyst in a chemical reaction. They are essential to obtain rates to sustain life as without enzymes rates would be too slow to provide for life. Molecules at the start of the process are called substrates, the enzyme will then convert these into changed molecules which are called products, after this process the enzymes maintains the same shape. (Berg et al. 2002).…

  • The Influence Of Enzymes

    Enzymes are substances produced by living organisms that act as catalysts to reduce the activation energy required for a chemical reaction. By lowering the activation energy, enzymes speed up the chemical reaction by providing an alternative action pathway (“Enzymes”). Enzymes are required in minute amounts because they remain unchanged after a reaction has occurred, so the same enzyme molecules can be reused over and over again. Since enzymes are proteins, they have active sites that speed up…

  • Enzyme Lab

    The objective of this lab was to see how enzymes were used, use the scientific method, and how enzymes are affected by temperature. Introduction Proteins which constitute enzymes in their final form are macromolecules that make up large amounts of living organism which are called polymers which are made up of many different monomers. An enzyme is a biological catalyst that increases the rate of a reaction by lowering activation energy. Activation energy that the enzyme uses id an energy barrier…

  • Peroxidase Enzymes

    Enzymes are biological catalysts that speed up the various chemical reactions that happen inside our cells. For the enzymes to function well, they need to be in an environment with a specific set of conditions, other than that it will lead to the denaturation of the enzyme or will render it completely inactive. There are a lot of factors that impact enzyme activities, but in this experiment we examined the effects of 4 different factors which are temperature, Ph level, addition of the inhibitor…

    the maximal velocity (Vmax) and the inhibition of alkaline phosphate. In order to accomplish these goals, 5 samples were used. Each sample contained different volumes of 0.2 m MPNPP (p-nitrophenylphosphate) and 0.2 M Tris-Hcl at a pH of 8.0. To each sample 0.2 mL of the enzyme studied (Alkaline Phosphatase) were added upon insertion on the spectrophotometer apparatus. With intervals of 20 seconds their absorbance at a wavelength of 410 nm was recorded at time frame of 2 minutes for each…

  • The Importance Of Enzyme Kinetics

    Enzymes are known as catalysts that cause reactions to occur more rapidly by lowering the reaction’s activation energy. A reaction’s activation energy is known as the minimum amount of energy required to get a chemical reaction started1. In order for cells to efficiently manage thousands of different chemical reactions, they make use of biological catalysts. Without these catalysts, biological reactions would not be able to proceed at a proper rate necessary to maintain life. Most, but not all,…

  • Enzyme-Substrate Complex

    catalyzed by enzymes. Without enzymes, most reactions necessary for the maintenance of life would occur so slow that they would not occur at all under the regular temperature and pressure conditions (Cooper). Enzymes act as catalysts that accelerate the rates of reactions by lowering the energy of activation. In an enzymatic reaction, the substrate (which is the reactant that an enzyme acts on) binds to the active site (which is the region on the enzyme where the substrate binds to) of the…

  • Chemistry: The Importance Of Enzymes

    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 enzyme, then many chemical reactions may not occur because the activation energy could be too high to be reached without the help of an enzyme. For example, table salt, or sucrose, could sit for years with no occurrence of hydrolysis, but after a few…
