Enzyme Activators and Inhibitors Lucia House AP Biology‚ Block 4 Mr. Trice October 18‚ 2012 Introduction: Metabolism is the totality of all of an organism’s chemical reactions. Chemical reactions occur due to enzymes‚ a substance which acts as a catalyst in driving chemical reactions in order to produce a desired product (Campbell and Reece‚ 2002). A catalyst is usually a protein; however‚ some catalytic molecules counter this generalization. A discovery made in the early nineteen- nineties

A Quantitative Enzyme Study: CATALASE FlowChart Purpose: Measure the rate of enzyme activity in different conditions Procedure: A. Extraction of Catalase 1. Peel potato 2. Cut into cubes 3. Mass 50g 4. Measure out 50ml of cold distilled water in blender 5. Add crushed ice into blender (small amount) 6. Add the potato cubes into the blender 7. Turn on blender on high for 30 seconds 8. Prepare an ice bath - FROM THIS POINT ON PREPERATION MUST BE CARRIED OUT IN AN ICE BATH – 9
Premium Catalase Hydrogen peroxide Enzyme
Enzyme Activity Lab Objective: To determine the effect of temperature‚ PH and enzyme concentration on catalase activity. Introduction: What is an enzyme and how the enzyme works. Any of a group of complex proteins or conjugated proteins thatare produced by living cells and act as catalysts in specific biochemical reactions. The system in which enzymes work is often referred to as the ’lock and key’ system it’s where the enzyme and the substrate lock together. The substrate then unlocks into
Premium PH Enzyme Catalase
Observing Enzyme Activity Purpose: The purpose of this experiment was to test whether the pH affected the enzyme reaction rate. Hypothesis: If the enzyme is in a basic solution‚ then it will react faster because the enzyme (catalase) reacts better in basic solutions. Materials: 10 potato cubes (1 cm3) -Pipet Baking soda solution -50 ml glass beaker Bleach Water Lemon juice Vinegar 5 glass test tubes Drying rack Timer Graduated cylinder Hydrogen peroxide Procedure:

The results provide evidence that when there was an increase in the sodium chloride concentration the mass of the potato prisms declined. At the zero percent concentration there was an increase of mass by 1.75%‚ from there the 1%‚ 3%‚ 5% and 10% begun on a downward trend with the percentage change in mass declining. The graph was on a steady decline from 0% being the highest point with a change of mass of 1.75% finishing with the 10% solution on a decline of -12.28%. From observing the scatter plot

10.10.2012 Internal assessment on enzyme concentration Enzymes are proteins that act as catalysts and they are the most important type of protein. My aim in this experiment was to investigate the effect of enzyme concentration on the rate of an enzyme (protease) – catalyzed reaction ‚ catalysts speed up chemical reactions . My hypothesis is that the rate as reaction will increase as the

I lived on a potato farm in Ireland during the Great Potato Famine. It was the worst famine in Europe in the 19th century. This famine started in September of 1845 and ended in 1852. During this time‚ life in Ireland was extremely difficult. We suffered from much starvation and disease. Approximately one million of us died and another million emigrated to other countries‚ especially America. The population of the country dropped 20 to 25%. The Great Famine began mysteriously. My family

The years during the mid 1840s to 1850s in Ireland were definitely not the best for many families‚ it was a time of tragedy. These were the years during the horrific times called the Irish Famine‚ also known as the Potato Famine or Great Hunger. The Irish Famine claimed innumerable amount of lives‚ leading to a “mass emigration of famine survivors to the United States” (McCallum). There were countless of families who emigrated to America during this catastrophe in order to escape starvation‚ poverty

The story of potato chips dates back to late 1850s‚ when a New York chef presented deep fried crisp potato chips to the railroad tycoon Cornelius Vanderbilt. Although the invention was made out of curiosity‚ it became an instant hit after Vanderbilt gave it an approval. Till date‚ potato chips are one of the most favorite snacks among many Americans. To keep up with the healthy trend at present‚ many chips makers now have baked alternatives to traditional chips. Here are few choices of our top chips
