Introduction: This experiment will investigate the factors that affect the rate of reaction of the enzyme catalyse‚ an enzyme found in food such as potato and liver. Catalyse is used to remove hydrogen peroxide from cells. The enzyme speeds up the rate of decomposition of hydrogen peroxide into water and oxygen. The reaction is: Catalyse is able to speed up the process because the enzyme lowers the activation energy of the reaction. This means that the free energy required for the reaction

What kind of role does hydrogen peroxide and a liver have in their chemical reaction? In the experiment‚ we saw they had a reaction‚ but completed further tests to determine whether they changed after the reaction. Hydrogen peroxide is chemically changed into water and the liver is broken down in the reaction. In the experiment‚ a fresh piece of chicken liver was put into a test tube filled with 3% hydrogen peroxide. We knew a reaction was taking place because the hydrogen peroxide started to foam

EXPERIMENT 1: Aim: To range the metals copper‚ lead‚ silver and zinc together with hydrogen. Start with the strongest reducing agent. Hypothesis: The nobler a metal is‚ the worse reducing agent. Apparatus/requirements: Sandpaper‚ strips of; zinc‚ lead‚ silver and copper‚ solutions containing aqueous; Zn2+‚ Pb2+‚ Cu2+ and Ag+ ions (0.2 M)‚ hydrochloric acid (5.0 M)‚ emery paper‚ test-tubes. Method: Burnish the three metal strips to get a shiny surface‚ after drop a drop of each of the metal

In my coursework I will investigate about enzymes in potatoes reacting with Hydrogen Peroxide. In particular I will investigate the effects of changing the surface area of a potato when added to Hydrogen Peroxide. This is because‚ when increasing the surface area of the potatoes it will increase the rate of reaction because there will be more surface area on which particles from the potato and the Hydrogen Peroxide will collide on‚ and with more surface area there would be more particles carrying

molecules be exposed to hydrogen peroxide. This will result in the rate of reaction increasing because it increases the chance of more successful collisions between the enzyme and the substrate. Catalase is an enzyme found in food such as‚ potato. It is used to break down a poisonous by-product of metabolism called hydrogen peroxide. Hydrogen peroxide is a compound that can kill cells therefore; it is essential that our body can break it up. Catalase breaks down hydrogen peroxide into oxygen and

Looking back at the research question‚ the actual amount of reactant did not match the theoretical stoichiometric amounts according to the balanced equation‚ but the amount of catalyst matched the original value when uncertainty is taken into account. The percent yields for the reactants in the equation are very far from 100% yield. In the case of water‚ the percent yield came out to be meaning there were at least 2 times to 4 times more water than there should be. The percent yield of oxygen came

Hydrogen has a high specific energy‚ high flame speed‚ wide range of flammability‚ and clean burning characteristics which suggest a possibility of high performance in internal combustion engines (ICE). These attributes have been realized for more than half a century since the onset of hydrogen engine development. In the early 1990s‚ FSEC conducted research on using hydrogen in an ICE. This work resulted in the development of a mixed fuel called HYTEST. Today‚ automobile manufacturers and DOE continue
