Investigate the Effect of pH on Immobilised Yeast Cells on the Breakdown of Hydrogen Peroxide Safety: ======= * Extreme alkaline and acids are used so must wear gloves, goggles and apron. * Be very careful not to make contact with any of the chemicals, as they will be irritable and some corrosive to the skin and eyes. * There must be no running and any other normal laboratory rules should be followed as usual. * Hydrogen peroxide is corrosive and so should not be touched. * A lab technician

Comparing Free to Immobilised Amylase Enzyme in Its Catalysis Rate Method: First of all, the Immobilised enzymes need to be made. The method used to create these immobilised enzymes would be Micro encapsulation. This means that the enzyme used, in this experiment being Amylase, is encapsulated inside Sodium alginate. The enzyme was believed to act quickly, so the enzyme would have to be slightly diluted in order to get a good range of results. !0cm³ of Amylase will be added to 20cm³ of

Effect of different size beads on the activity of immobilised catalyse Aim: To find out how varying the size of beads containing yeast varies the rate of activity of catalase in a fermentation reaction of hydrogen peroxide with immobilised enzymes. A catalyst is a substance that speeds up the rate of a chemical reaction, without itself being used up in the process however it maybe affected physically i.e. degradation of the surface of the catalyst. Catalysts work by reducing the activation

which involves the use of harvesting enzymes from microorganisms. The production of enzymes from bacteria and fungi can be isolated from the growth media and cleansed and purified as necessary. Generally in industrial processes the enzyme is immobilised which allows t h enzyme to be re-used and also enable the products to be separated easily. The production of textiles, paper, leather fruit juices and biological detergents are produced from Microbial enzymes. ======================================================================

the enzyme can no longer function. Immobilised enzymes are attached to inert insoluble materials so that the enzymes can be held in place during the reaction, removed and reused. Enzymes are used in industry because they speed up reactions producing products which can be used as they are, or can be used to make different products. They can be used whilst within cells or micro-organisms, or they can be extracted and isolated. They are often immobilised once extracted, so that the enzymes

the growth of microorganisms. As they grew larger then fines (goods and raw materials) in the industry can be imposed this pollution and can cause a big loss. Aim: To investigate how the concentration of glucose is increased over time if immobilised lactose (enzyme is added to the whey) Hypothesis: The whey can be produce by adding rennet to the milk to separate the lactose from the cream. My hypothesis is that is no glucose present in whey originally but as the enzyme is added then

The Uses of Enzymes in Industry and Medicine Enzymes are used in a wide range of industries for a number of reasons, the main one being that they accelerate reactions by lowering the activation energy. Enzymes are proteins with specifically shaped active sights that have charges on their surfaces. This means that they react with only one substrate to produce a specific product minimising the production of unwanted by-products. They work at neutral pH and standard atmospheric temperature

Would whey protein supplementation decrease muscle atrophy in immobile Special Forces soldiers during Special Support and Reconnaissance missions? Introduction Watching silently from a concealed position lays an elite soldier on a Special Support and Reconnaissance (SSR) mission. Less then one hundred metres from the enemy, that soldier may be required to lie there unmoving and undetected for long periods, days to weeks at a time. During this time his muscles are slowly beginning to atrophy

The Uses of Enzymes In Industry, Medicine and Analytical and Diagnostic Processes Enzymes are very precise protein molecules with a high specificity which are used to catalyse chemical reactions by lowering the activation energy required for the reaction to take place. It is these properties of being able to break down substances easily and bind specifically to certain chemicals that make enzymes very useful in many industries and practices throughout the world. In addition to this enzymes

Third Battle of Ypres Officially known as the Third Battle of Ypres, Passchendaele became infamous not only for the scale of casualties, but also for the mud. Ypres was the principal town within a salient (or bulge) in the British lines and the
