INTRODUCTION TO SITE INVESTIGATION Site investigation is the study of the local environment and ground conditions on and around a specific piece of land. This is used to ascertain the suitability of a site for a proposed building project: The condition & strength of the soil Details of any man-made or natural hazards present on the site The economic viability of the site There may be three components‚ the walkover survey‚ the desk study and the ground investigation. 1.

reaction will be highest. This relate to other resources‚ such as books and the internet‚ which show that the optimum pH value for catalase is pH7‚ therefore there is no difference between the optimum pH and the pH used in the experiment‚ hence the enzyme structure is not affected by the pH and is most active. However the graph inadequately supports the second part of the prediction‚ that the rate will be lowest‚ the more acidic or alkaline the pH level is. For instance when the rate starts of

Enzyme Kinetics Examples and Problems 1. An enzyme is produced for producing a sun protection lotion. Given kinetic data for the enzyme reaction with Vm=2.5 mmol/m3.s‚ Km=8.9 mM and So=12mM‚ what would be the time required for 95% conversion in a batch reactor? 2. An enzyme was assayed at an initial substrate concentration of 10-5M. The Km’ for the substrate is 2x10-3M. At the end of 1 min‚ 2% of the substrate had been converted to product. a. What % of the substrate will be converted

Investigation into how pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples. Catalase is a type of enzyme that is found widespread among organisms that grow in the presence of oxygen (almost all living things) its specific use is to speed up the decomposition of Hydrogen peroxide (H2O2) within cells. Hydrogen peroxide is a bi-product

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

INTRODUCTION OF ENZYMES Enzymes are complex proteins that cause a specific chemical change in all parts of the body (David C. Dugdale‚ 2011). When we understand enzymes we understand cells (Marshall Brian‚ 2001). In many organisms most chemical reactions are catalyzed -when a substance speeds up the rate of a chemical reaction- by enzymes. Each enzyme controls a certain function that happens in a cell. Still each one has its own process and rate that it converts molecules. Studying enzymes shows how chemical

Investigation of the rate of photosynthesis of pondweed. Research question: How does the concentration of sodium bicarbonate relate to the amount of oxygen produced by Elodea (Canadian pond weed) in the process of photosynthesis? Hypothesis: If there is an increase in concentration of sodium bicarbonate the amount of oxygen produced will increase because the sodium bicarbonate concentration will increase the carbon dioxide levels. Independent variable- Concentrations of sodium bicarbonate (8%
