Effect of Temperature on Peroxidase Ability to Break Down H2O2 By: Rodneika Crutcher Abstract Temperature affects the ability of peroxidase to break down hydrogen peroxide. In this experiment our professor extracted peroxidase from potato tissue. In order to determine how temperature affects peroxidase we created solutions and measured their absorbance levels after water bath treatments. The more absorbent the solution was the less hydrogen peroxide there was in the solution. This means the peroxidase

An investigation to compare the reaction rates between potato and hydrogen peroxide against liver and hydrogen peroxide through loss in mass. Background information: Catalase is an enzyme that is found in all cells. This means that it is an intracellular enzyme. And enzyme is a biological catalyst. A catalyst is some thing that speeds up a reaction without being changed itself. Because of this enzymes and catalysts can be used again and again. Enzymes are protein chains that have a primary‚ secondary

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 kinetic energy‚ and by carrying

pineapple’s skin extract on Candida albicans. Instruments The researchers will use Candida albicans that they will buy from University of the Philippines Los Baños (UPLB). The fungus‚ then‚ will be divided into three setups: Set A‚ Set B‚ and Set C. Each set will contain Candida albicans placed in a Petri dish. These sets will be given different amounts of the Pineapple skin’s soap extract; Set A will be given 40%‚ Set B will be given 70% and Set C will be given 90% of the soap extract. The researchers

There are many things that were‚ are and are very likely to stay incomprehensible for us therefore causing perpetual anguished reflections and arguments for many generations of people. Some of these things are objective‚ natural phenomena in the world around us like the blue colour of the sky or the instinct of different birds and fish which always leads them home. But also there are such things like Good and Evil‚ Love and Hatred‚ Honesty and Betrayal‚ Self-sacrifice and Egoism‚ Eternity and Transiency

INTRODUCTION According to Wikipedia‚ fuel is any material that stores energy that can later be extracted to perform mechanical work in a controlled manner. A fuel contains energy‚ mostly heat‚ which can be released and then manipulated. Most fuels used by humans undergo combustion‚ a redox reaction in which a combustible substance releases energy after it ignites and reacts with the oxygen in the air. Other processes used to convert fuel into energy include various other exothermic chemical

Mortality Rate of Termites Sprayed With Yemane Decoction and Chili Extract Chapter 1 – Introduction Background of the Study Using natural pest and disease control is often cheaper than applying chemical pesticides because products and materials which are already in the home and around the farm are most often used. Termites are small‚ white‚ tan or black insects. It belongs to the insect order Isoptera‚ an ancient insect group that dates back more than 100 million years. Termites also

The aim of this experiment was to investigate the effects of salt type and concentrations on the rate of heating and the boiling point. Then from this data make a conclusion which salt type and concentration is the most energy efficient at heating water to its boiling point. It was hypothesised that highest concentration of MgCl2 was going to be the most energy efficient at heating the solution to its boiling point. This is because MgCl2 has the lowest specific heat capacity thus will use the least

An investigation how sugar solutions of different concentrations affect osmosis. Research Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution to one of a higher concentration. If a solution has a low concentration then the amount of (in the case of my investigation) sugar‚ the solute‚ will be low and the solution will be weak. If there is high amount of sugar then the solution will be concentrated (have a high concentration). When two solutions
