foam that can be measured. ANALYSIS QUESTIONS 1. a) Describe the effect of damaging the potato on the catalase activity. With the increased level of damage to the potato‚ there appeared to be more activity within the reaction between the catalase and the H2O2. b) Explain at the cell level why crushing or macerating the potato has this effect. When you crush or macerate the potato‚ you are breaking the cell walls of each individual cell. Once this happens‚ the catalase is

Title: Osmosis and water potential Aim of the experiment: Finding the water potential of potato. Biological principles: Independent variable: concentration of the solution. Dependent variable: percentage changed in weight of the potato strips. Controlled variable: size of the potato strips‚ it can be controlled by cutting the length of the strips. Procedure: Table 1. Concentration of sucrose solution table Concentration/ M | Sucrose Solution/ ml | Distilled

Battery from Potato Introduction: Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. We are wondering if we can use any other liquid as electrolyte? This gave us the idea of using a potato as electrolyte. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte. Problem: Can Potato be used to generate

Investigation into how pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples. Catalase is a type of enzyme that is found widespread among organisms that grow in the presence of oxygen (almost all living things) its specific use is to speed up the decomposition of Hydrogen peroxide (H2O2) within cells. Hydrogen peroxide is a bi-product
