Coursework - Biology Aim An Investigation into the rate of the decomposition of hydrogen peroxide into oxygen and water using the enzyme 'catalase'. Prediction I think that the amount of gas I collect will be directly related to the temperature that the solution is at. I think that the higher the temperature, the more gas I will collect, until the enzyme is denatured. Once the enzyme is denatured the amount of gas I collect will drop quickly. Also I think hydrogen bonds will play a part in this reaction, these are where atoms of hydrogen attract and form together. Here is an explanation of how enzymes work: SUBSTRATE ENZYME Inside the cell, enzymes and substrates move around. Enzymes have been created by the cells, and substrates are the by-products of the reactions within the cells. When an enzyme and a substrate collide, they join together. Once they are joined, the enzyme can begin working. It attempts to bring...
