Test Tube Degrees Celsius
1,267 wordsEnzyme Action: Testing Catalase Activity Enzymes are proteins that serve as catalysts and accelerate chemical reactions in living organisms. Enzymes accomplish this by lowering the energy of activation of the organism it is acting upon, however enzymes will only lower the energy of activation for specific organisms, reducing chaotic chemical reactions. The reaction is carried out in its entirety in the active site of the enzyme. The substrate (organism acted upon), binds itself into the active s...

Effects Of Acid Rain Sulphur Dioxide
868 wordsThe damaging effects of acid rain on society is becoming overwhelmed with great amounts of pollution from cars, factories and an large amounts of garbage. The immense amounts of sulphur dioxide put into the air causes high levels of acid in the atmosphere. When this sulphuric acid is absorbed into moisture in the air, then rain can be harmful to the environment. Acid rain is destroying lots of things in our environment. It is hurting lakes, air and thew rest of our ecosystem. Acid rain is killin...

Acid Mine Drainage Causes Effects And Solutions
1,484 wordsFor hundreds, even thousands of years, human beings have mined for metals and stones, and with the advent of greater technology as well as greater needs, the demands for these resources continue to grow. While these resources benefit our lives in many ways, the effects of mining can be detrimental, and one such effect is the topic of this essay, acid mine drainage (A. M. D. ). The causes of A. M. D. will be discussed, along with some of the physical and biological problems associated with it. So...

Investigation On The Enzyme Trypsin
2,197 wordsAn Investigation determining a factor affecting the rate of digestion of gelatin by the protease trypsin. Introduction An enzyme is a biological catalyst, which speeds up reactions. An example of this in the human body is trypsin (a protease produced in the pancreas and used in the stomach), which catalyses the digestion of gelatine, a protein. For this investigation, a photographic film will be the source of the gelatine. I will be able to identify when the gelatine is digested, when the photog...

2 O 2 Bodies Of Water
1,333 wordsAcid rain pollution comes in various forms. Whether its toxic waste, CFCs, or sewage, they are all hazardous to the earth. These can deplete the earth and its inhabitants of resources, causing a harmful change. A product of pollution is acid rain. We shall see that acidification is harmful to all forms of life. Acid rain is any form of precipitation that is polluted by sulphur dioxide (SO 2), and nitrogen oxides (NOX). This acid precipitation can be in the form of rain, snow, sleet, fog, or clou...

Petri Dishes Flowering Plants
3,855 wordsIs there an effect on Rhizobium bacteria by changing its pH? Steve Lincoln Period 3 12 / 7 / 98 Question What are the effects of varying pH levels on Rhizobium bacteria, and can a pH resistant Rhizobium culture be grown? Hypothesis Alterations of the balanced habitat such as the change of pH levels can drastically alter the life of bacteria and can directly affect chemical reactions of enzymes released by the bacteria. Using this information the change in pH will have an effect on the Rhizobium ...

Degrees Celsius Test Tubes
1,993 wordsEffects of Temperature, pH, and Gelatin on Bromelain Introduction Bromelain is an organic catalyst that speeds up the rate of chemical reactions. Bromelain is used in this experiment to catalyze the break down of proteins and is called a proteolytic enzyme. Enzymes enable reactions to occur at a lower temperature and energy levels. This allows many reactions to occur inside living organisms that would otherwise have been impossible to take place. This enzyme is found in fruits, leaves, and stems...

Baking Soda Hydrogen Ions
2,207 wordsHow pH of Soil affects a Plants Growth For the experimental aspect of the research report, four sets of two plants are to be studied. They must either be checked according to size for the same height, or started from seed to ensure equality. Two identical sets of roses are to be cultivated, as well as two sets of corn plants. The flora must all be given the same amount of water and sunlight each day. The only variable to be changed is pH. One of each set will be planted in the acidic soil, and o...

Baking Soda Hydrochloric Acid
3,324 wordsAim: To find which powder, of four, is best for neutralising excess stomach acid. Prediction: With stomach pain relief powders being a consumer product, I predict that the best cure for neutralising a build up of stomach acid will be the one which has the lowest cost to successfully neutralise the dilute hydrochloric acid (HCl) (0. 5 mol) (to represent the excess acid found in our stomachs). This powder would have be the one which costs less than any of the others to bring the acid build up to a...
