8/12/2013 Intro I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules of one substrate. The site of the reaction occurs in an area on

and Virology. The objective of my thesis was to produce and characterize thermostable β-Galactosidase enzyme‚ which has been explored in various biotechnological‚ industrial‚ medical and analytical applications. The focus of research was not only limited to thermo stability of β-Galactosidase‚ but also to the production of large amount of enzyme in a short period of time. The β-Galactosidase enzyme hydrolyzes lactose into galactooligosaccharides‚ which are suitable for lactose-intolerant people and

The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved

summarized by the equation: . Enzymes play a very significant part in respiration. During the different stages of respiration‚ enzymes that are often found in the matrix of the mitochondria are used to speed up reactions in the body by reducing a reaction’s activation energy‚ which means that less energy is required to start a reaction. Enzymes need to collide with their respective substrates in order to generate a reaction‚ increasing the temperature will give the enzymes and their substrates more energy

Core Practical: Enzyme concentrations and enzyme activity. Introduction In this experiment I shall investigate how the enzyme concentration can affect the initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis

BIOLOGY HSC NOTES MAINTAINING A BALANCE • Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates. Enzymes are protein molecules that allow the body to engage in chemical reactions‚ such as metabolism. There activities can be catalytic (being able to control the rate of either increasing/decreasing chemical reaction) Enzymes have a specific shape‚ and this shape must be intact‚ otherwise the effectiveness

ACT 2 SCENE 2 INTRODUCTION Good afternoon. I’m going to tell you about the disposition of Julius Caesar’s wife Calpurnia‚ during the early morning hours on the Ides of March which was also the day Caesar was to be crowned king but‚ was assassinated instead. BRIEF SUMMARY The scene opens with thunder and lightning accompanied by torrential rain since the night before when Calpurnia is deeply disturbed by horrid nightmares of Caesar being slaughtered by sadistic murderers (sadistic because they were

Identify an issue of global significance which introduces a conflict of concepts and values. Examine the facts‚ language‚ statistics‚ and images used by at least two sides in the conflict in their representation of the issue. In the process‚ identify assumptions‚ justifications‚ values‚ and emotions which diverge. To what extent can you find the truth of the issue? 1. Poverty (also more specifically beggars and begging) 2. Social concepts of time (e.g. Mainstream concepts vs. First Nations’ concepts)
