"To See What Factors Affect The Decomposition Of Hydrogen Peroxide By The Enzyme Catalase Which Is Found In The Liver" Introduction: Enzymes are biological catalysts. They speed up the chemical reactions which go on inside living things. Without them the reactions would be so slow that life would grind to a halt. Enzymes work by when a substrate molecule bumps into a molecule of the right enzyme‚ it fits into a depression on the surface of the enzyme molecule. This depression is called the

Assess the relative importance of physical and human factors in causing change in ecosystems (30 marks) Both human and physical factors impact upon ecosystems due to their holistic nature which means that even small changes in the human or physical environment around them can cause an exponential chain of results. However these factors can be both positive and negative to varying degrees. Some of the most obvious physical factors which cause change in ecosystems can be seen through succession;

Niels Bohr’s model of the hydrogen atom‚ was the primary reason for the understanding of energy levels.Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns‚ scientists believed electrons could be described as waves. Bohr hypothesized that energy is being added to the hydrogen gas in the electricity form‚ and then leaving the gas in the form of light. He figured the light rays to be quantized‚ meaning only certain frequencies of

com/fatherofchemistry Objective To determine the activation energy for the reduction of peroxodisulphate(VI) ions. S2O82-‚ by iodide ions I-‚ using a ’clock’ reaction. Principle The equation for reduction of S2O82- by I- is: S2O82- + 2I- → 2SO42- + I2 The formation of iodine is ’monitored’ by small & known amount of thiosulphate ions‚ S2O32-: 2S2O32- + I2 → S4O62- + 2I- Once the reactants are mixed

High Frequency? Or Insider Trading? Dow Intraday Trading May 9th 2010 High frequency trading has reached a point in which its legality needs to be called in to question. These traders hurt markets and other investors while forcing large investors to move into dark pools. High frequency traders also have an unfair advantage when it comes to trading. The above picture shows the most infamous trading crash caused by high frequency traders known to date. The Dow Jones Industrial average fell

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

An Investigation on the rate of reaction of the enzyme Catalase on the substrate Hydrogen peroxide. Plan Aim: To investigate the rate of the effect of Catalase on hydrogen peroxide. Introduction This investigation will be carried out to investigate the rate of reaction of the enzyme catalase on the substrate hydrogen peroxide. Enzymes are biological catalysts‚ which speed up the rate of reaction without being used up during the reaction‚ which take place in living organisms. They do this by
