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

Potatoes as Other Point of Supply for Batteries I. Background of the Study For the past few years‚ researcher Rabinowitch and colleagues have been pushing the idea of “potato power” to deliver energy to people cut off from electricity grids. As a resident living in the Philippines wherein most perilous typhoons happen‚ Filipinos experience tough challenges like the cut off of the electricity or most people say “brownout”

TUI UNIVERSITY George M. Cyrus Jr Module 2 Case Assignment Logistics 501 Tom Javarinis Let’s look at how the potato chip came to be. In 1853 the first potato chip was invented by a chef at the Saratoga Springs New York resort in 1853. It was created because one of the customers at the resort keep sending them back because they were too thick‚ soggy and had no taste to it. Crum then decided to fry them and sprinkled them with salt for taste. They

the 1920s‚ immigrants poured into the United States for many different reasons. Immigrants were faced with challenges such as saving and spending money‚ blending with others and the Potato Famine in Ireland. Immigrants were treated differently on their appearances‚ the way they speak and customs they had. The potato famine in Ireland drove the Irish from their homeland to America. Some immigrants‚ English was a primary language‚ for others learning a new language would be difficult. Immigrants moved

I had also recorded the results less often and made the tests longer.

nature. Who is the subject and who is the object? Who really is domesticating who? From a plant’s eye‚ he challenges the traditional relationship of human and nature and presents the argument that the four plants- Apples‚ Tulips‚ Marijuana and the Potato have shaped human evolution just like we shaped theirs. He calls it “co-evolution”. Nature plays a part in controlling us. It is what the plants know about our desires that made them grow‚ survive and spread around the world until today. Each has

how a specific pH level would impact tyrosinase activity. First we added 4.0 mL of pH in each corresponding test tube and then added 0.5 mL of substrate (catechol) into each test tube. In the instructions it says to apply your 0.5 mL of tyrosinase (potato extract) as well but you have to blank the spectrophotometer before. The results from this experiment confirms that our hypothesis of a neutral pH displaying a stronger impact on tyrosinase is true. According to our results the pH levels at a more

Effect of an Orange on Catalase Activity in Comparison with a Potato Introduction Catalysts are substances that increase chemical reactions while using less energy. They also remain unchanged after use‚ which enables it to be used repeatedly. Cells have special catalysts called enzymes‚ which are specialized proteins that help accelerate chemical cell reactions. (Evert‚ RF & Eichhorn‚ SE 2013). Enzymes also control plant metabolic processes such as respiration (Evert RF‚ Eichhorn SE & Perry JB
