    Ashley Esparza Stallings Period 2 January 26‚ 2013 Enzyme Catalysis Lab Report Background: Enzymes are catalyst‚ which affect the rate of a chemical reaction. One consequence includes the cell to carry out complex chemical activities at relatively low temperatures. In these reactions the substrate binds reversibly to the active site. The cause of this is a decrease in the energy needed to activate the reaction of the substrate molecule to from products. Every enzyme is particular for a

    The effect temperature has on the activity of the enzyme α- amylase. Introduction Enzymes are a biological catalysts‚ which means that they speed up the chemical reactions in living organisms. Almost all of enzymes are energized protein molecules that catalyse and regulate nearly all biochemical reactions that occur within the human body. The reason in which enzymes are sensitive to heat‚ pH and heavy metal ions is because they are made up of proteins. The food we eat is turned into energy by enzymes

    (Justification-2 Enzyme Inhibition) By quantitative balance‚ the total amount of Enzyme is [E] 0= [E] + [EI] + [ES] + [ESI]. By using a=1+[I]/KI and a′=1+[I]/K′I‚ it is followed by [E]0=[E]a+[ES]a′ This equation can be written like this‚ [E]0=(Km[ES])/([S]0)a + [ES]a′=[ES]( aKm/[S}0+a’)‚ because of Km=[E][S]/[ES] and [S]≈[S]0. V=kb [ES] =kb [E] 0/ (aKm/[s] 0+a’). Kb [E] 0 is Vmax. This is why V=Vmax/(a^’+aKm/[S]0). This equation can be rearranged like this‚ 1/V= a’/Vmax+(aKm/Vmax)1/[S]0‚ which is

    LOGOS INTERNATIONAL SCHOOL INNOVATORS CAUGHT IN ACTION: HOW DOES CHEMICAL ENGINEERING AFFECT THE SUDDENLY CHANGING WORLD? Ponhneath Nguon College and Careers Preparation Class Mr. Barrett “But innovation comes from people meeting up in the hallways or calling each other at 10:30 at night with a new idea‚ or because they realized something that shoots holes in how we’ve been thinking about a problem.” -Steve Jobs. It is quite unbelievable how the world has changed so rapidly over the last

    explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions (Raven‚ 2011). It helps accelerate reactions by lowering the activation energy‚ which is needed for reactions in cells to progress at a higher rate (Kaiser‚ 2001). Activation energy is the minimum amount of energy needed for a chemical reaction to occur‚ yielding products from a given set of reactants. Products are results of an enzyme cleaving to a specific

    catechol which‚ when exposed to the air‚ becomes oxidized by the oxygen in the air and produces benzoquinone‚ which makes the apple appear brown (Andrew Clapper’s Online Journal‚ 2007). This chemical reaction is catalyzed by the enzyme catechol oxidase (Figure A.1). Enzymes are proteins in cells that speed up chemical reactions (Enzyme Procedure Guide‚ 2013). The catechol oxidase lowers the amount of energy needed in order for the catechol to be oxidized‚ which speeds the process up. Fig. A.1: The

    Factors Affecting Rates of Chemical Reactions Prepared By: Kelly Gunter For: Ms. Brohman Course: SCH-4U Introduction The main purpose of this lab was to investigate how temperature‚ concentration‚ the addition of catalysts‚ and the substitution of a more reactive reactant‚ can affect the reaction. The collision theory explains that in order for a reaction to occur‚ reacting particles must collide with one another. An effective collision makes reactants result in a reaction and

    Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. In the enzyme lab‚ the effects of concentration‚ temperature and pH on the functionality of the enzyme catalase. The enzyme lab was also about measuring reactions by capturing the oxygen that was generated by the reaction. Materials and Methods: Experiment 1‚ 2‚ & 3 Experiment 1 examined the effects of concentration on catalase activity. Experiment 2 examined the effects of concentration in temperature
