the rate of catalase activity The extent at which environmental factors affect the rate of catalase activity was discovered in this lab. The assay system‚ in which a filter paper disc was dipped into the enzyme and submerged using a stirring rod in a test tube filled with 20mL of hydrogen peroxide‚ was used to test several enzyme factors. As the saturation of hydrogen peroxide increased the rate of reaction increased as well. When the enzyme concentration increased the rate of catalase activity

were able to witness a chemical take place and products being produced. The same ingredients that were used in part one of this lab are used in this part‚ but in contrast to part one this part will vary the pH of the enzyme solution. The enzyme‚ again‚ is catalase‚ the substrate is hydrogen peroxide‚ and the products are the oxygen bubbles that are produced. Also‚ in this lab the time it takes for each disc to rise to the surface of the hydrogen peroxide solution determines which pH the reaction occurs

and oxygen produced by the potatoes catalase reacting with hydrogen peroxide) was a kind of indicator of how the reaction was going. It almost indirectly related to the temperature increase‚ because every time the temperature was rising there also seemed to be foam also rising at the top of the hydrogen peroxide. As you can compare when the temperature started rising in my tests‚ my observations would also have a correlation to the foam produced by the catalase.

a way society can interact with both the world of information and physical world is the “SixthSense” project. The SixthSense project is an idea started by Pranav Mistry and his associates from the Fluid Interfaces Group based out of the MIT Media lab. This organization has many projects which are all founded on a few common goals. This goal can come to fruition by focusing on innovations. These Innovations include enhancing the experience of using technology by implementing ways to make the experience

Background Information: Enzymes such as catalase are globular protein molecules with catalytic properties. A catalyst is a substrate which can alter the rate of reaction without itself undergoing any permanent change. As they are not changed
