Action Of Enzyme Catalase On Hydrogen Peroxide Lab Report

Action Of Enzyme Catalase On Hydrogen Peroxide - Lab Report Example The student feels that the more the concentration of the liver the more the enzyme that would result since more amount of oxygen would react with the hydrogen peroxide molecules. For accomplishing this, the student has taken five test tubes with the first test tube having twice the suspension as that of the fifth tube expecting that there would be twice the amount of oxygen given off. This seems that the student wants to prove that the amount of oxygen that would be evolved would be directly proportional to the amount of the liver suspension take. Since it cannot be decided in a single experiment the student repeats it three times to observe whether the desired changes have taken place in each experiment or not. The independent variable to be considered here would be the amount of liver suspension and distilled water and the dependent variable would be the amount of oxygen evolved. This experiment deals with quantitative analysis. The overall experiment can be summed up by the following table (Note: Exp indicates experiment) It can be observed that there is a significant variation in the amount of oxygen evolved in the three experiments. The variation can be clearly understood observing the graph below It can be inferred from the graph that there is a gradual decline in the amount of oxygen evolved considering the concentrations of the enzyme. (The x-axis represents experiment and the y-axis represents the amount of oxygen evolved). It is only in the second experiment that the discrepancy arises. It is highly probable that there might have been a replacement of the suspension. It can be clearly understood that there is a direct relationship between the amount of suspension and the amount of oxygen evolved. The experiment is in fact a relatively simple one and can be performed easily if the conditions are ideal. The student has done it appropriately and has a good analytic skill. The prediction is purely based on understanding as it involves mainly quantitative analysis rather than the chemical reaction. The student has opted the right materials for accomplishing this experiment. The only requirement would be to do the experiment under perfect conditions and conduct the experiment singly so as not to confuse with other experiments. The following experiment would boost the above observation Hypothesis: Iftime is increased, then more hydrogen peroxide molecules will be split into water and

International business - ideas international - Essay Example ver, Hindi is the main language in which most of the high budget films are getting introduced in the market, and Bollywood is the front face of the Indian film industry. The Bollywood has earned an international repute for its excellence in the field of film production. The liberalized foreign investment regime has given a tremendous opportunity to the foreign film makers. But, the foreign film production company should remember that the India is a very sensitive market as far as the films are concern. There are many religions, languages and rituals are practiced in India so, before making a film these points should be clarified as the films are one of the main mass Medias in India. The Film World is a private limited company. It was found in late seventies in Melbourne, Australia. It is having a vast experience in producing high quality films in the Australia and in the international market. The film world is one of the upcoming films production companies in the Australia. The company is packed with full of talented work force. It believes in producing quality work. It has many successful achievements throughout the journey for more than two decades. In the mid of eighties that is in 1985, the FilmWorld ventured into the film production and distribution in Kuala Lumpur, Malaysia. The early ninety was a great time for the company as it was going through a tremendous success in the Australia and Malaysia. During the last few years the company is producing approximately four films in Australia and three films in Malaysia in a yearly basis. Due to the recent advancement, the company is looking for the opportunities in the Indian film market. India has the world’s biggest film industry in terms of number of movies produced in a year; it is almost eight hundred movies yearly. It works efficiently as one of the great sectors for the foreign investment. However, for any foreign investors the background check is very important and there lies the importance of the
