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

Abstract Enzyme catalysis was observed in order to analyze how changes in temperature‚ pH‚ enzyme concentration‚ and substrate concentration affected an enzyme-catalyzed reaction. This experiment analyzed the rate of enzyme-catalyzed reactions and observed the correlation between catalase activity and products formed. It was found out that the rate of an enzyme-catalyzed reaction starts off rapidly‚ decreases‚ and levels off or completely stops‚ and can be further affected by environmental factors

Cintya G. Alarcon Donna Biology 121 section WDF Lab Report # 1 1.On the graph paper in Figure 3‚ plot a graph of your experimental results. Choose an appropriate number scale for the Y-axis and label it Number of Infections. Choose an appropriate number scale for the X-axis label it Number of Exchanges. 2. In a few sentences‚ summarize the results of the experiment. In your summary‚ include data from your summary chart and graph. Statements of results should include only facts—no interpretation

water with no chlorine. Clean an area of space you think is suitable‚ preferably lab tables. Take out 5 beakers. Take out an electric mass scale. Turn on electric mass scale (power button) and place a beaker on top of the scale. Make sure to only measure one beaker at a time. Wait till the digits on the screen slow down and stop at a number. The number it stopped at‚ that is the number you will right down in your lab book (that you will get out) as scrap notes. After you have measured each beaker

Name: Mugabe Rodrigue Class: Grade 11B Subject: Biology Topic: DNA Extraction From Onion Date: 20/1/2014 Introduction: DNA‚ or deoxyribonucleic acid‚ is the hereditary material in organisms. Nearly every cell in an organism has the same DNA. Most DNA is located in the cell nucleus.The information in DNA is stored as a code made up of four chemical bases: adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). The order‚ or sequence‚ of these bases determines the information available for

Enzyme Report Case 1 - Hereditary Fructose Intolerance 1 & 2. Enzymes take on a variety of roles in the human body at the cellular level. Specifically‚ they aid in the breakdown of macronutrients such as glucose and fructose so that the body can use them. Although reactions within the body would occur without enzymes‚ enzymes provide control because the reaction is not needed all of the time. Enzymes function in specific environments such as temperature or pH; some enzymes are specific

too long (shriveling is a common misconception)‚ a tea bag’s contents diffuse through the water. These are all examples of diffusion and osmosis. These phenomena happen everyday and people don’t realize what is actually happening. The purpose of the lab is to see the effects of diffusion and osmosis. In part B‚ the higher the concentration of solute‚ the higher the mass of the solution. Methods and Materials: For part A of the experiment‚ the following items are needed: Dialysis tubing‚ IKI solution

The purpose of this review paper is to discuss the effect of temperature on enzyme- catalyzed reactions. This is relevant because many diseases can be diagnosed and controlled by the processes of enzyme activity (Worthington 2015). If more information is not found about enzyme activity and how it is affected‚ many diseases may go undiagnosed and uncontrolled. Temperature is a type measurement that does not only consist of heat. It is the measurement of the mean kinetic energy of any group of particles
Premium Enzyme Chemical reaction Catalysis
Structure: Enzymes are globular proteins that act as catalysts‚ they have a specific 3D shape that is the result of their amino acid sequence. There is a specific region of the enzyme that is functional‚ this is called the active site. The active site is made up of a small number of amino acids and forms a small depression within the larger enzyme molecule. Moreover‚ the molecule that the enzyme acts upon (substrate) fits precisely into the depression and forms an enzyme-substrate complex. The substrate

in these reactions‚ resource‚ products and enzyme are three most mainly things. In all chemical reactions‚ there is a activation energy(EA) needed for them. However‚ if the rate of reactions are too low‚ they will not be able to sustain lives. In this case‚ they have enzyme as a protein catalyst. As reaction catalysts‚ enzymes are proteins that adjust the process by initiating the reaction. In this case‚ there are also many elements that influence enzyme working rates. For example‚ most living things
