The Effect Of Substrate Concentration On The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase

farnborough collage Problem in employee absenteeism and concentration to the workplace. Introduction: This report is based on small business organization which contains all kinds of crockery items. There are seven people works in the large shop (one manager and six sales people). On the busy hour some of sales person are missing in a regular basis and also some of staff can not able to mange customer needs though shop got s lots of verity in products. Staffs go for smoke or tea without asking

“The first essential for the child’s development is concentration. It lays the whole basis for his character and social behavior‚ he must find out how to concentrate‚ and for this he needs things to concentrate upon…” The Absorbent Mind‚ Chapter 22 Discuss how the Montessori Education helps to develop a child’s concentration and helps the child in his social development. In order to accomplish any task you need to be able to concentrate

Insertion and amplification of EGFP protein into pET41a(+) Plasmid Introduction The overall purpose of the experiments conducted is to test the creation of recombinant plasmid using recombinant DNA technology. The research of recombinant DNA began with the use of E.Coli (Escherichia coli)‚ a common bacteria found in the intestines of warm-blooded or- ganisms (5). Scientists worked together and generated a way‚ from cloning and using recombi- nant research‚ to achieve recombinant DNA

The concentration of power in an absolute and parliamentary monarchy develops from the different ruling styles and development pattern of the region. This is most clearly seen in Europe‚ where both systems of governing are in effect. In England‚ a parliamentary monarchy is seen due to England’s tyrannical monarchs‚ producing a series of revolts ending in the weakening of royal power. Fear of certain religious dominance during the Renaissance period also caused the beheading of many monarchs‚ revealing

DETERMINATION OF ERYTHROSINE CONCENTRATION USING UV- VISIBLE SPECTROPHOTOMETER INTRODUCTION In chemistry‚ spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. It is more specific than the general term electromagnetic spectroscopy in that spectrophotometry deals with visible light‚ near-ultraviolet‚ and near-infrared‚ but does not cover time-resolved spectroscopic techniques. Spectrophotometry involves the use of a

How Enzyme Concentration can Affect Rate of Reaction The purpose of this investigation was to see how the concentration of an enzyme affected the rate at which a substance was broken down. We did this by using a white protein called casein. Casein is found in milk powder‚ it is a protein and used mainly as a binding agent in foods‚ because it is mad to proteins and joins to a phosphoric acid it belong to a group called the phophoproteins. In terms of in milk it is said to be healthier if it is

All cells have the same basic structure (see figure 1) however some cells are specialised to suit a specific purpose. An example of this is the pancreatic beta cells found in the islets of Langerhans. These cells are specialised to synthesise the protein insulin that is involved in the metabolism of glucose in the cells. (Layden‚ 2010) Figure 1 - Picture to show basic structure of a cell. (Farrabee‚ M J. 2007) But how is insulin made? The production of insulin starts in the nucleus which is the

The effect of increasing substrate concentration on rate of an enzyme reaction. Enzymes are biological catalysts that lower a reactions activation energy making possible many of the reactions needed for life to exist. Enzymes have a high specificity which have been explained by many theories such as Fischer’s lock and key. Currently the most widely accepted theory is the induced fit hypothesis proposed by Koshland in 1958. This hypothesis solves some of the problems with the Lock and key theory

Aim: To investigate the effect of hydrogen peroxide concentration on enzyme catalase Indroduction: Enzymes are proteins. They function as biological catalysts. They lower the energy barrier of a reaction so that the reaction can take place at body temperature. Also‚ they can speed up Metabolic reactions without being changed or used up. During a reaction‚ an enzyme molecule combines temporarily with the substrate. When the reaction is complete‚ the enzyme molecules returns to its original dorm
