Introduction When companies begin to dominate the local market most of the time they would want to expand their horizons to the outside world where it could either make great strides or horrible losses.Corinthia Hotels is a Maltese founded company which began from a beautiful villa around 40 years ago in Malta that has now spread to Europe and north Africa in countries like Hungary‚Portugal‚Russia‚Czech republic and Libya.The success of this company has been brought about by careful analysis of

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

Natalie Drossoyianni I.B 1 Psychology HL Discuss the use of technology in investigating cognitive processes. Technology has been very useful for the past few years in investigating cognitive process. With the use of neuro-imaging techniques‚ researchers can examine brain structure and function‚ and thus understand better the relationship between cognition and physiology. The basic neuro-imaging techniques are the PET‚ the MRI‚ and THE fMRI scan. The PET or else the positron emission tomography

Biology Digestive Enzyme Experiment “Design an experiment in which you will investigate a digestive enzyme’s effect on digestion” Research Question: To determine the effect of enzyme concentration on the rate of digestion. This will be done by increasing the concentration of the enzyme diastase and investigate its effect on the rate of starch digestion. The rate will be determined by the amount of time it takes to completely digest the powdered starch‚ the complete digestion will be indicated by

tenderizer did not break down as much as the cup â»3 with the most tenderizer. Conclusion According to this lab it demonstrated that Jell-O does have protein since the enzymes in the meat tenderizer were able to break down the Jell-O and prevent it from setting. This data also shows that the amount of enzymes effects the breakdown of proteins since the cup with the least amount of meat tenderizer set better than the cup with the most amount of meat tenderizerizer CUP NUMBER OBSERVATIONS

Research question: What is the effect of altering the pH of the solution that pieces of apple are placed into on the degree of colour change that occurs when the pieces of cut apple come into contact with atmospheric oxygen‚ as measured by a colour scale? Hypothesis: Altering the pH of solution that pieces of apple are placed into has an effect on the degree of colour change that occurs when they come into contact with atmospheric oxygen. As the pH of solution increases‚ so does the degree

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

Principles of Biology Lab Exercise Enzymes: Catalysts of Life Instructor: Professor Alcendor By Shahid Rana Date: March 7th‚ 2013 Abstract: In this experiment we have demonstrated the function of enzymes. The whole experiment was devoted to understand how enzymes work as a catalysts and increase the chemical reaction without being used themselves. In general‚ enzymes are proteins that function as biological catalysts. These enzymes adhere to lower to amount of energy required for
