Part one1. a) When hydrogen peroxide was added to manganese, tiny bubbles formed in the solution- intensity of (1).b)The solution did not change in temperature.c) The bubbles stopped forming after about 18 minutes.2. After we added 2 more mL of hydrogen peroxide, the reaction occurred again. Again, small bubbles formed; intensity of (1). The solution did not change in temperature. The reaction lasted about 15 minutes.3. After adding more manganese dioxide, the reaction occurred again. This time, the bubbles being formed were larger; intensity of (4). The solution got a little warmer, but the difference in temperature was hardly distinguishable by simply touching the test tube. The reaction lasted about 10 minutes.4. a) The hydrogen peroxide is used up and the manganese dioxide remains unchanged.Part twoTitle: Enzyme FunctionPurpose: To observe the role of enzymes in chemical reactions and to determine the kinds of cells that contain more of the enzyme catalase.Prior Knowledge:Enzymes are proteins that assist the chemical reactions of a cell by lowering the amount of activation energy needed to start the reactions, thereby enabling the cell to carry out the reactions at a faster rate; enzymes that lower the activation energy are therefore called catalysts. Moreover, the enzyme itself is not destroyed in the process. Hydrogen peroxide is a substrate broken down into oxygen and water by the enzyme catalase. Sand and chalk are nonliving, so they do not have catalysts. Spinach and potatoes have enzymes to help speed up chemosynthesis and create a byproduct of hydrogen peroxide. Ground beef and cooked liver both have a high amount of enzymes because they are found in heterotrophic living organisms.Hypothesis/predictionsWe thought that the level of intensity and heat in the different test tubes would go in this order from greatest to least: raw liver, raw hamburger, boiled liver, potato, spinach leaf, calk, and finally sand.We based our hypothesis on the idea that living things have enzymes to speed up chemical reactions. The raw liver and hamburger would have the most since they were the ones that were least altered from a living thing.The boiled liver was next since heat can distort enzymes, and if too many enzymes had their shapes changed by heat, they would not be able to break down the hydrogen peroxide as efficiently, or not at all. Next came the 2 plants.We predicted chalk and sand to be the least reactive, since they are nonliving and probably...

We used hydroxylamine as the inhibitor, which resulted in fully deactivating the enzyme. INTRODUCTION: The purpose of this lab report is to better understand the relationship of the enzyme itself its reactions, and how anything can essentially affect the activity of the enzyme. The chemical reactions that we studied were under the

Chemical reations is an essay on chemical reactions in Chemistry.

1944 words - 8 pages Chemical ReactionsChemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter.Later, in the Seventeenth Century, a German chemist named Georg Ernst Stahl was the first to postulate on chemical reaction, specifically, combustion. He said that a substance called

So it’s purification on large scale is required for different commercial and research purposes. The enzymes have been isolated from different sources, which include bacteria, fungi, organs of mammals and invertebrates, but a little have been reported in plants. Commercially available alkaline phosphatases (APase) are Bacterial and

The role and function of religion in society.

1914 words - 8 pages social solidarity is reinforced, deviant behaviour is restrained and social change restricted. In maintaining social solidarity, religion acts as a conservative force. When it fails to perform this function new ideas emerge, which become the new religion. So Durkheim regarded Nationalism and Communism as the new religions of industrial society, taking over from Christianity but performing the same essential functions. As a result Durkheim and other

The Advantages of using Enzymes in Biotechnology.

1159 words - 5 pages The Advantages of using Enzymes in BiotechnologyBiotechnology is the use of biological processes to exploit and manipulate living organisms and biological systems to develop or manufacture a product that is a solution to a problem.An enzyme is a protein, which is able to catalyse biochemical reactions. Reactions need to exceed their activation energy in order to take place. Enzymes reduce the need for activation energy and so allow reactions to

Lab Report on Measuring the Rate of Conversion of Hydrogen Peroxide using Enzyme Catalysis

866 words - 3 pages lab was also an opportunity to see a catalyzed reaction in a controlled experiment. And the last objective was to learn how environmental factors affect the rate of enzyme catalyzed reactions. Enzymes are proteins produced by living cells. They act as catalysts in biochemical reactions. A catalyst speeds up the rate of a chemical reaction and makes it possible for the reaction to occur with a lower initial input of energy. One benefit of

1152 words - 5 pages The Applications of Enzymes in Industry and Medicine Enzymes have a wide range of applications and they are used in industry and in medicine to perform numerous different tasks to get specific results. The market for commercially produced enzymes is catalysts is very large because enzymes are used in reactions to speed up a specific process therefore making the process cheaper for the company since they work best in

The Industrial Application of Enzymes

1995 words - 8 pages work with one specific substrate. The purpose of an enzyme is to lower the activation energy required for biochemical reactions to take place. As a result a reaction catalysed by an enzyme will be much more efficient at breaking down a substrate into its products and consequently are used in industry for just this purpose. To obtain these enzymes scientist look mostly tonaturally occurring microorganisms, as they are the

Without them, the rate of the reactions would be so slow as to cause serious, if not fatal, damage. Without enzymes toxins would soon build up and the supply of respiratory substrate would decrease. Enzymes are proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules of one
