Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending

Enzyme Activity Over Different Concentrations and Effects The goals of this experiment were to examine the effectively of enzymes on samples of different enzyme concentrations and substrate concentrations. In addition‚ the experiment tested how effective enzymes are on samples of pH levels and temperature levels. A. Effect of Enzyme Concentration Hypothesis: With half as much enzyme concentration then the reaction rate will be half as much than when the enzyme concentration is equal

sentiment was demonstrated by the “Spirit of ‘76”‚ a common patriotic attitude that was present in America. Primarily focusing on a hope for liberty and equality‚ the “Spirit of ‘76” was felt by many Americans‚ and radicals such as John Adams and Thomas Jefferson popularized its message. Still the thirteen colonies were not united‚ and it was a known fact that union was essential to declaring independence or else it would fail. This caused radicals to begin spreading the positive effects of independence

Enzymes (pron.: /ˈɛnzaɪmz/) are large biological molecules responsible for the thousands of chemical interconversions that sustain life.[1][2] They are highly selective catalysts‚ greatly accelerating both the rate and specificity of metabolic reactions‚ from the digestion of food to the synthesis of DNA. Most enzymes are proteins‚ although some catalytic RNA molecules have been identified. Enzymes adopt a specific three-dimensional structure‚ and may employ organic (e.g. biotin) and inorganic (e

Reactions Enzymes are proteins found in living things that speed up chemical reactions. They aid in nearly all metabolic processes‚ such as food digestion‚ molecule synthesis‚ and the storage/ release of energy. An enzyme speeds up the rate of the chemical reactions by lowering the reaction’s activation energy‚ which means that by definition‚ an enzyme functions as biological catalyst. The activation energy is the energy that is used to get a reaction started. The function of an enzyme is dependent

The Enhanced Greenhouse Effect The greenhouse effect is the effect of heat in the atmosphere which is causing more problems in the earth. The gases in the atmosphere‚ warmth from the sun would rebound back into space. Lot of gas in the air causes a large amount heat to be engrossed into the atmosphere also the heat of the sun’s energy warmth the world’s atmosphere. This Enhanced Green House effect experiment is to demonstrate that earth’s heat may be increasing because of the atmosphere in earth

MISEP Chemistry 512 – Jacobs Enzyme Catalyst Lab - Formal Report – August 8‚ 2007 ABSTRACT This investigation examined what would happen to the rate of an enzyme-catalyzed reaction if the concentration of substrate changed. We hypothesized that if the concentration increased‚ then the reaction rate would also increase. To test our question‚ we varied a combination of substrate and buffer‚ totaling 6mL‚ with a constant amount of 2 drops of catalyst. The enzyme catalyst‚ peroxidase‚ increased

Less guns‚ Less crime? “‘If a preschool child hits another child with a rock‚ the solution is not for every child to have a rock!”’(NICHOLS) More gun control is needed with the advances of fire arms. Getting a gun is far too easy in America. A person can obtain a firearm the day they walk into a gun store and hands over the money. The absence of more gun control is helping these crimes occur more often‚ this is allowing citizens to obtain guns easily. “Right now‚ State officials‚ local authorities
