Osmosis in potato cells Aim: To view and examine the effect different concentrations of sucrose solution has on the movement of water across the cell membrane. Hypothesis: That the potatoes will either increase or decrease in mass‚ due to the effect of the different concentrations. Osmosis will occur. Apparatus: * Fresh potatoes * Apple corer * Scalpel * Petri dishes X 10 * 50ml measuring cylinder * Distilled water * Paper towelling * Sucrose solutions:

investigate the concentration of enzyme as we had previously investigated the optimum temperature for catalase in the preliminary investigation. Concentration of enzyme is also fairly easy to investigate‚ as you need to only increase the amount of potato that you want to investigate at a given time. Hypothesis As the concentration of enzyme increases it will have an effect on the rate of reaction. The suggested optimum will be 10g as the higher the mass of catalase the more enzymes‚ meaning

Concentration‚ pH and Temperature on Enzyme Activity” Abstract: In the following experiments we will measure precise amounts of potato extract as well as Phenylthiourea‚ combined with or without deionized water and in some instances change the temperature and observe and record the reaction. We will also investigate the different levels of prepared pH on varying samples of the potato extract and the Phenylthiourea and record the results. We will answer question such as what is the best temperature for optimum
Premium Buffer solution Enzyme PH
I predict that if the potato has a neutral pH (close to 7)‚ then the function of catalase will be at its maximum capacity because our bodies have a neutral pH and our livers‚ which contain catalase‚ work perfectly fine even in these conditions. This study is worth pursuing because
Premium Enzyme Oxygen Hydrogen peroxide
Abstract: Enzymes‚ molecules that speed up chemical reactions‚ are specific to one substrate. In this experiment the substrate hydrogen peroxide and the enzyme catalase will be used. The higher the concentration of potato extract‚ or catalase‚ the faster the reaction and the more substrate present will result in a decrease in the time of the reaction. The amount of concentrations of enzymes and substrates are changed to determine if the reaction is further catalyzed by a greater concentration of
