Six Factors Affecting the Performance of an Enzyme Enzymes are considered catalysts; substances that increase the rates of reactions. Enzymes are responsible for thousands of metabolic processes that involve the sustainment of life‚ one common one is simple food digestion. Without enzymes‚ digestion would occur too slowly for life to continue. Enzymes maintain a protein structure consisting of one or possibly more than one polypeptide chains of defined primary structure‚ and take up a characteristic

The purpose of this study was to observe the effect of different concentrations of sodium chloride have on the germination of lettuce seeds‚ Lactuca sativa. A study done by Katembe et al.‚ (1998) stated that an increase in salt solution in the environment of the seed will slow down water imbibition‚ therefore‚ preventing germination and root growth. The prediction for this experiment was that lettuce seeds‚ Lactuca sativa‚ having a higher concentration of salt in their environment will have a lower

Project Enzymes are organic catalysts produced by living organisms which aid in the progression of specific biochemical reactions without undergoing any permanent chemical changes themselves. They are complex‚ conjugated proteins necessary and required to sustain life. Today‚ enzymes are also used world-wide in a variety of different industrial applications such as the production of paper‚ wine fermentation‚ and bio-remediation. One of the most important industrial applications enzymes are used

of this experiment was to find the relationship between temperature and the enzyme activity of amylase. This was achieved by attaining amylase enzyme‚ starch solution and potassium iodide (determines if enzymes hydrolyses the starch solution)‚ water bath and a hot plate. The temperatures used for this experiment were room temperature‚ 37oC‚ 60oC‚ 80oC‚ and 90oC. The hypothesis developed was that as the temperature increased‚ so will enzyme activity. Therefore‚ the ability of the enzyme to break

Received July 18‚ 1997X A radiochemical enzyme assay for studying cyclooxygenase (COX)-catalyzed prostaglandin biosynthesis in vitro was optimized with respect to both COX-1 and COX-2 activity. The assay can be used to assess the relative selectivity of plant-derived inhibitors on COX-1 and COX-2. Assay conditions were optimized for both enzymes with respect to concentration of cofactors (l-epinephrine‚ reduced glutathione‚ and hematin)‚ activation time (enzyme and cofactors)‚ reaction time‚ and

CHAPTER 1 INTRODUCTION A. Background of the Study Concentration has been defined as the ability to direct one’s thinking in whatever direction one would intend. Concentration plays vital roles in doing well in studies. A student has to work really hard and concentrate firmly to get concepts well in mind. All students have the ability to concentrate some of the time. But at other times students’ thoughts are scattered‚ and their minds race from one thing to another. They don’t have the ability to

Lab Report Enzymes (must be typed) Name: Amanda Gallegos Date: 2/15/15 Section: BIOL 101GL What is the Hypothesis of this experiment? (3 points) -The highest temperature will affect the reaction rate of enzymes. What is the dependent variable? (1 point) -Change of rate/product/color/absorbency. What is the independent variable? (1 pt) -The temperature. Explain in detail the procedure that you followed (including amount of substrate‚ enzyme etc‚ and the whole procedure including incubation times)

I. Preparation A. Choosing 1. You should choose the fruits that you like. a. For example‚ if you desire to gain more different fruits enzymes or make the glass bottle more colorful‚ you can choose four or even more kind of fruits. There is no limitation. But‚ you must include one fruit‚ lemon. It helps to kill the bacteria of the drink. B. Composing 1. The ratio of components should be 3‚ 1. It means 3 parts of fruits‚ 1 part of sugar. You can follow this ratio to determine the amount of fruit

Effects of Allelopathy on Plants Dates experiment was conducted: Purpose: The purpose of this experiment is to design a controlled experiment to see if a plant could survive living in eucalyptus tea. Allelopathy is when a plant gives off a bio-chemical that kills that plants around it‚ such as eucalyptus trees‚ black walnut trees‚ etc. My class went to the a eucalyptus grove and observed the eucalyptus trees. We noticed that there was a small circle around the tree that had nothing growing

RUNNING HEAD: Understanding Enzymes Understanding Enzymes Amanda Chung Blanche Ely High School Abstract The researcher conducted this experiment in order to investigate how various factors effected enzymes. Those factors were the concentration of the enzyme‚ the temperature it had to work in‚ and the pH level of the solutions as well. All three were hypothesized to speed up the rate at which the enzyme acted. A series of several tests were carried out to find the answer to each problem
