1) Discuss the social identity issues present in the case Social Identity theory basically is a theory that explains self-concept (what a person thinks about themself and how they analyze themselves) to be a combination of personal identity – their unique characteristics and social identity – their membership in different social groups. There are numerous Social Identity issues in the case. Firstly‚ Catherine’s father is an accountant which is one of the factors that she chooses to be an accountant

classroom assessment to support learning. However‚ the ‘accountability’ juggernaut was not for turning‚ even though the Blair dynasty’s clarion call of “Education! Education! Education!” had not yet begun to ring hollow. It was the day we decided to up the ante and make it our target to resurrect assessment by teachers‚ not to abandon testing‚ but to refocus assessment activities where they should be‚ on pupil learning. The King’s College pair had been long-term advocates of formative assessment

of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills‚ the experiment was done in order to determine how the rate of reaction will be altered‚ whether it will increase‚ decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant‚ animal‚ and microbial cell. There are thousands of different enzyme can be found in any cell. Enzymes can be describe as molecules

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

But the 3% took almost the whole 7 minutes to finish rising in temperature. So essentially‚ the higher the concentration of hydrogen peroxide‚ the faster the reaction will take place. Furthermore‚ the foam (water and oxygen produced by the potatoes catalase reacting with hydrogen peroxide) was a kind of indicator of how the reaction was going. It almost indirectly related to the temperature increase‚ because every time the temperature was rising there also seemed to be foam also rising at the

Enzymes Reactions to Changes in Substrate and Inhibitors Benjamin J. Mora Coronado University of Texas Rio Grande Valley at Edinburgh Abstract Purpose for the experiments was to test the enzymes in various scenarios and see how changing this would affect the rate of reaction. The enzyme source used in the experiments was Turnip Extract. Concentrations of Turnip extract for activity 1 where o.5ml‚ 1.0ml‚ and 2.0 ml as for the rest of the activities 2 Through 4 stayed at a consistent concentration

Enzymes: Food & Nutrition What are enzymes Enzymes are a type of protein produced by a living organism used to catalyze chemical reactions in cells. These reactions allow the cell to build things or take things apart as needed in order to grow and reproduce. How do enzymes work - in steps 1) Substrate floats near enzyme 2) Substrate and enzyme connect – which breaks it into products 3) Products are released ex) BreadFast & Co.’s use of enzymes The company uses many different
