... say this because there will be more H2O2 for the enzyme to react with than if the concentration were less. If i increase the concentration of the enzyme i predict that more oxygen will be produced and at a faster rate this is because there will be more catalase to breakdown ... more oxygen will be produced. Most enzymes if cooled stop working at all. Method 1. Put all coats and bags out of the way, tie back long hair and tuck in ties. Put on your goggles. 2.

... in size. This is because the cell is fully plasmolysed and no more water can leave the cell. Apparatus For the experiment you will require: Cylinders of potato with a diameter of 6.5mm a borer with a diameter of 6.5mm Sucrose solution of varying strengths (ranging from 0M to 1M) A burette to measure out the sucrose solution. Six jar specimen bottles Razor blade Method We take a cylinder ... contract in strong solutions (low water concentration). This is due to osmosis, where water passes from weak solutions to strong solutions across a semi-permeable membrane, such as a cell membrane. T...
