Enzyme Lab 6 03/13/2013 Report by Mary Jo Anthony I. Introduction II. Materials and Methods III. Results IV. Conclusion and Discussion Introduction Background Information: This lab allowed us to study chemical reactions and how catalysts will affect the rate of these reactions. The reaction we studied is the breakdown of hydrogen peroxide to water and oxygen and it is vital to life. The molecule hydrogen peroxide is a molecule that is toxic

Potato Enzyme Lab INTRODUCTION An enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism. A good rule of thumb is to remember that enzyme names end in “-ase”. This will help in identifying enzymes in further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The

Factors Affecting The rate of Enzyme Activity Prediction: As the temperature increases the rate of enzyme activity will also increase‚ thus increasing the rate of reaction. However‚ if the temperature is too high the enzyme will denature. Materials: 4 test tubes 2 small beakers A dozen filter paper disks Test tube rack Hydrogen peroxide (H2O2) Potato extract Forceps Thermometer Hot plate Large beaker Ice cubes Graduated cylinder Stopwatch Procedure: Step 1 Place 10 mL of potato

This experiment was performed in order to analyze the effects of pH‚ enzyme concentration‚ and temperature on the catalytic rate on enzyme ALP. The initial experiment was done to approximate the optimum pH for the activity of the enzyme. The hypothesis was that alkaline phosphatase activity will be critically affected by pH effects. The hypothesis was valid because the data shows that the pH values for the acidic‚ basic‚ and neutral tubes increased over time‚ absorbing at similar rates. The basic

Discovery Equals Recovery Discovery can be defined as “the act or instance of discovering something new” (Discovery). While recovery can be defined as “the regaining of or possibility of regaining something lost or taken away” (Recovery). Many people believe that to discover something is to find something completely new. This is not always the case. The discovery might only be new to the person doing the discovering. The idea that discovery equals recovery can easily be seen in the Renaissance

| [pic] Introduction Enzymes are catalysts which speed up a reaction by providing an alternative reaction pathway of lower activation energy. But they do not undergo permanent changes and so they remain unchanged even at the end of the reaction. Many enzymes consist of proteins and non-proteins called the cofactor. The intra- and intermolecular bonds that hold proteins in their secondary

intensive exploration and colonization of the world. Some of the many motives for exploration were that the Europeans wanted prestige‚ power‚ wealth‚ and to convert individuals to Christianity. Some historians often refer to this as the Age of Discovery‚ in which the Portuguese and Spaniards play a major role during this time. After an outbreak in Europe on the 14th century known as the Black Death‚ caused about 25 million people to die over a five-year period. This made Europe go through a major

Temperature and pH on Enzyme Function Chelsie Mesa Section 0479 Robin Cotter Introduction The purpose of this experiment is to identify three unknown enzymes. This is done by using different temperature and pH to affect the function of the enzyme‚ which ultimately‚ will affect how much maltose is produced. Enzymes are proteins that help catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process are called substrates‚ and the enzyme converts them

Journey of Self Discovery Self discovery was a process I thought I had already been through. But when faced with the question‚ “Who am I?” it proved to be a lot harder to put into words than one would think. I believe that I have a good sense of who I am‚ but translating it into words was a struggle for me. I consider myself to be a very concrete thinker. So‚ the translation of who I am into words tended to come out as cold and rigid. Words like brash‚ concrete‚ smart‚ and loyal seemed like

Description: A peroxidase enzyme‚ which was extracted from a brassica compestris (turnip)‚ is tested under various conditions in temperature‚ pH level‚ and competitive inhibitor (hydroxylamine). ABSTRACT: In order to determine the properties of an enzyme‚ a peroxidase enzyme was extracted from a brassica compestris (turnip) and tested under various temperatures‚ pH levels‚ and by a competitive inhibitor (hydroxylamine). The enzyme activity was measured in various ways depending on the activity
