Computer Enzyme Action: Testing Catalase Activity 6A H2O2 is toxic to most living organisms. Many organisms are capable of enzymatically destroying the H2O2 before it can do much damage. H2O2 can be converted to oxygen and water‚ as follows: 2 H2O2 → 2 H2O + O2 Although this reaction occurs spontaneously‚ enzymes increase the rate considerably. At least two different enzymes are known to catalyze this reaction: catalase‚ found in animals and protists‚ and peroxidase‚ found in plants. A great

diffusion I will be using potato discs‚ of the same size and mass‚ in different concentrations of sugar solution to find out whether the mass of the discs increases or decreases depending on the concentration. I predict that when the sugar solution is 0% the mass will increase as there is less sugar in the water than in the potato. The water will then travel through a partly permeable membrane into the potato from outside. When the sugar solution is 20% the mass of the potato will decrease as there

1. The decision making process for canned tuna is as follows: (i) Problem Recognition Consumers of canned tuna are motivated primarily by the need to satisfy their physiological need of hunger which is the most basic level of needs under Maslow’s hierarchy of needs. Problem recognition can also stem from stock-outs where consumers run out of canned tuna supplies. In addition‚ motivation of purchase can be marketer-induced to incite new needs/wants by introducing consumers new uses of canned tuna

Potato Batteries: Veggie power! Data and Analysis Background The battery was invented around 1800 by Alessandro Volta in Italy. It has become an indispensable part of modern life. Why are batteries so useful? Because they convert chemical energy into electrical energy. You can use this electrical energy to light a flashlight‚ to start a car‚ or to listen to your favorite music. We made a simple battery out of a potato by placing in it a zinc strip and a copper strip. At the zinc strip‚ the

Osmosis using potato cores and sucrose solution 1.0 Abstract This experiment’s ultimate goal is to find the water potential of the potato cell. This was achieved through placing potato cores in different concentrations of sucrose (0.2%‚ 0.4%‚ 0.6%‚ 0.8%‚ 1.0%‚ 2.0%‚ 3.0% and 4.0%) solution and to observe how much water was gained or lost through osmosis to reach a prediction of the concentration within the potato cell. The results displayed that the concentration of sucrose within the potato cell is

have messed up there. We were supposed to store them in a carton upside down for 2-3 days at 75 degrees before they were to be put in the incubator and we did not do that. There is only an 80% hatching rate as well so we may have just had the two chickens that were in the 20 percentile sadly. Many things may have caused them to not grow. It’s like hunting
