    10.10.2012 Internal assessment on enzyme concentration Enzymes are proteins that act as catalysts and they are the most important type of protein. My aim in this experiment was to investigate the effect of enzyme concentration on the rate of an enzyme (protease) – catalyzed reaction ‚ catalysts speed up chemical reactions . My hypothesis is that the rate as reaction will increase as the

    This experiment is to determine the unknown DNA plasmid using restriction enzymes and conducting electrophoresis finally comparing the resulting fragments with the known restriction map. In this lab‚ it succeeds in showing the fragments. In this report we will discuss the‚ results‚ limitations and possible errors. Introduction In biology restriction enzymes are used in several ways to modify and manipulate DNA molecules. One common use is to compare pieces of DNA from one that is unknown‚ with fragments

    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

    DISCUSSION: Bromelian added to Gelatin: Bromelian is an enzyme found in pineapples. When Bromelian is added to gelatin it breaks down the protein and does not allow the gelatin to solidify. There are several factors that can cause an enzyme to slow down or to completely stop reacting. For example‚ temperature and pH can effect enzyme activity. Canned pineapple juice and fresh pineapple juice were used to see how the enzyme would react differently. In fresh pineapple juice the Bromelian have would

    Biology Enzymes IA Design Introduction: Enzymes are globular proteins‚ they are responsible for most of the chemical activities of a living organism. They act as catalysts‚ substances that affects the reaction of other substances without being destroyed or altered during the process. They are extremely efficient in the body system of living organisms‚ one enzyme may catalyse over a thousand chemical reactions every second. But there are certain conditions that need to be fulfilled in order for the

    Enzyme Controlled Reactions 1) Describe the relationship between substrate concentration and the initial reaction rate of an enzyme-catalyzed reaction. Is this a linear relationship? What happens to the initial reaction rate as substrate concentration increases? A) The relationship between the substrate concentration and the initial reaction of an enzyme-catalyzed reaction is very productive‚ but is dramatically affected by the pH level of the given solution. The most productive pH level is

    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

    Enzymes are proteins that increase or decrease the rate of chemical reactions. They are generally globular proteins and are around 62 amino acids residues in size. What enzymes do is determined by their 2-dimensional shape. A lot of enzymes are bigger than the substrate they act on‚ but only a little part of the enzyme involved directly with the catalysis. Without enzymes the chemical reactions in the body‚ would be so slow‚ the body would shut down. And cell reactions would take too much energy
