Lab Report (Effect of concentration on enzyme activity) Biology Noor Alawadhi 11- KC Introduction: An Enzyme is a protein‚ which is capable of starting a chemical reaction‚ which involves the formation or breakage of chemical bonds. A substrate is the surface or material on or from which an organism lives‚ grows‚ or obtains its nourishment. In this case it is hydrogen peroxide. This lab report will be explaining the experiment held to understand the effects of the changes in the amount of

Norovirus Many people are affected each year by what is commonly misdiagnosed as “stomach flu.” However‚ the medical term for this condition is Norovirus. The Norovirus is also known as Norwalk-like viruses‚ SRSV (small round structured viruses)‚ or “winter vomiting disease” as it often affects the host during the winter months. The condition may come upon the sufferer at any time; not just during the winter months. SRSV is a grouping of a number of viruses‚ which is the most common

College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded

Enzyme Activity Over Different Concentrations and Effects The goals of this experiment were to examine the effectively of enzymes on samples of different enzyme concentrations and substrate concentrations. In addition‚ the experiment tested how effective enzymes are on samples of pH levels and temperature levels. A. Effect of Enzyme Concentration Hypothesis: With half as much enzyme concentration then the reaction rate will be half as much than when the enzyme concentration is equal

Investigation on Effects of Different pH on Enzyme Activity How does the different pH buffers affect activity of potato enzyme/extract? Introduction: Proteins are polymers that are made up of smaller units/monomers called amino acids. There are 20 different types of amino acids‚ thus make up many different combinations in types‚ numbers of amino acids as well as their orders – an explanantion for why there are so many proteins. Every protein‚ due to various reactions of amino acids to each

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

The Effects of varying p-Nitrophenyl Phosphate concentrations on Alkaline Phosphatase Activity Nathan Overholt Louis Settembrino March 5‚ 2002 Abstract: The enzyme Alkaline Phosphatase was set up in solutions of varying p-nitrophenyl phosphate concentrations. A fixed time assay was used to find the Michaelis constant and Vmax. All solutions were incubated at 30 C° for 30 mins. Absorbances were measured at 405 nm‚ and the Km was found to be 0.002 M (pNPP) and the Vmax to be 0.433 A/min. Introduction:

Out of the three stories that we have read the most engaging in my opinion was ‘The Chosen Vessel". The short story written by Barbra Baynton deals with topics like superstition and religion‚ showing the deadly outcomes of these themes. These themes first caught my attention as it is something that differentiates for many people depending on when and where you are. I was interested in the religious history of Australia and really liked how Baynton told the story of Australian religious history through

The Effect of Starch on the Activity of Amylase with pH Variable Lab Report‚ Fall 2011 East Tennessee State University Department of Biological Sciences By: Shelby Brackett Date Performed: October 10‚ 2011 Lab Instructor: Joseph Kusi Biology 1111‚ Section 018 Abstract Enzymes are very important in chemical reactions. They are used to speed up the reaction taking place. They act by binding to a specific substrate and form an enzyme-substrate complex that may put stress on chemical bonds
