Aim: To investigate the action of the enzyme catalyse Hydrogen Peroxide Water + Oxygen 2 H2 02 2H2 0 + 02 Hydrogen peroxide is a poisonous waste product in chemical reactions. Catalyse converts it to water and oxygen rapidly. Factors affecting reaction P.H Concentration of Hydrogen Peroxide Temperature Concentration of catalyze in potato Prediction I think that the greater the surface area of catalyst the faster the reaction will occur, this is because there is more chance of the molecules colliding with each other because there are more enzymes and...
get a bung that sealed so it was all right. Instead of trying to use a conical flask, we could have used a gas syringe to collect the oxygen in. This would be more accurate because there is less chance of losing any oxygen, because it is a direct connection and unlikely to leak or move out of position. If we had more time we could of done some further experiments like, Using different potatoes, changing the concentration of the hydrogen peroxide, or changing the temperature the experiment was done at enzymes work best at 30 to 40c.

Scientific Back round: Osmosis is defined as the net movement of water or any other solution's molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially permeable membrane such as...

Aim The aim of the investigation is to see the effect light intensity has on the rate of photosynthesis. Background Information The rate of photosynthesis is affected by a number of factors including light intensity, temperature, water, carbon dioxide and availability of nutrients. If the conditions the...

Definition of Osmosis Osmosis is the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low water concentration. Hypothesis I predict that the lower the concentration of the sugar solution in the test tube, the...

Background Information ?â?£ There are three main types of Enzymes. These are Carbohydrases, Protease and Lipases. ?â?£ Enzymes can be used over and over again. ?â?£ If the temperature is too low the Substrate Starch has less thermal energy which means that there will be...

Planning: I am investigating the effect of increasing enzyme concentration on the rate of reaction. Prelimary work is very important and I conducted this before carrying out my final experiment. It is important because I need to find out which was the best vegetable to use,...
