    Chloride (NaCl) Concentration Had on the Rate of Reaction of Catecholase Enzymes in a Potato (Solanum tuberosum). Abstract Enzymes are a key component of a cell. They make chemical reactions happen faster because they lower the activation energy to make the chemical reaction occur. Most of the time‚ it is best if enzymes produce as efficiently as possible‚ but in some cases it is better if they do not‚ when dealing with potatoes (Solanum tuberosum). If the catecholase enzyme of the potato is hindered

    Different Concentrations of the Enzyme Catechol Oxidase on the Rate of Benzoquinone Production When Mixed with Pure Catechol Carson Levine November 4th‚ 2013 Abstract Catechol oxidase is an enzyme that speeds up the oxidation reaction when catechol is exposed to oxygen. When the reaction occurs‚ benzoquinone is produced turning the oxidized substance brown. It was hypothesized that the higher the concentration of catechol oxidase‚ the browner the substance will

    NaCl Effects on Peroxidase Activity My experiment was to see if adding NaCl to solution would have any effects on peroxidase activity. The materials that were used in this experiment were pH 7 buffer(DI water)‚ peroxidase‚ NaCl‚ guaiacol and hydrogen peroxide; added in that order. Blanks were created for each NaCl concentration‚ 0%‚ 5%‚ 7.5% and 10%. Each cuvette had .5ml of pH 7 buffer‚ 1ml of peroxidase‚ .02ml guaiacol for the experimental cuvettes and 0ml of guaiacol for the blank cuvettes‚

    conditions in potato juice extract Introduction The presence of quinones prevents infection of microorganisms because it is toxic to them (Danyk‚ H‚ 2013). Quinones are produced by the oxidation of phenolic compound of catechol. Enzymes are used to speed up chemical reactions in cells (Danyk‚ H‚ 2013). The enzyme catechol oxidase is used to speed up the production of benzoquinone which is to help in infection prevention. In this study catechol oxidase was combined with potato juice extract

    Studying the Rate of Reaction of catechol oxidase and how it affects pH levels Introduction: In this lab‚ we studied the activity of an enzyme that is found in fruits and vegetables called catecholase or catechol oxidase. An enzyme is a protein molecule that is a catalyst. Catechol oxidase is the enzyme in fruits and vegetables that turns them that undesirable brownish color; also commonly referred to as bruising or bruised. When walking through your regular grocery store and you find yourself in

    drops of catechol were added to each of the tubes. To equal out the amount of solution in each of the test tubes‚ respectively 23‚ 22‚ 20‚ 16‚ 8 and 0 drops of pH 7 buffer were added. 30 drops of potato juice containing the catechol oxidase enzyme were then added to the solution‚ and then timed for 5 minutes at room temperature. The pH treatment only required 5 test tubes‚ with 3mL of matching buffer (pH4‚ pH6‚ pH7‚ pH8‚ and pH10) in the appropriate tube. Following this‚ 10 drops of both potato juice

    2) Why is your study significant‚ i.e.‚ how is your objective relevant/applicable to the larger world and why would the information you seek be important/valuable to others? (either in terms of using catechol oxidase as a model to study enzyme function or considering the specific activity of catechol oxidase) 3) State your hypothesis (an educated prediction): Materials and Methods 1) List specific materials used in your experiments (and sources of these materials).

    compounds. In this experiment however‚ the only reaction being tested is the oxidation of catechol (a diphenol) by the enzyme catalyst catechol oxidase or polyphenol oxidase‚ which initiates a chain of reactions and eventually triggers the formation of brown pigments known as catechol-melanins. Catechol‚ also called 1‚2-dihydroxybenzene is a phenolic compound with the chemical formula C6H4(OH)2. The catechol molecule consists of two hydroxyl groups bonded to a central benzene ring‚ hence the molecule

    The potato is a starchy‚ tuberous crop from the perennial Solanum tuberosum of the Solanaceae family (also known as the nightshades). The word may refer to the plant itself as well as the edible tuber. In the region of the Andes‚ there are some other closely related cultivated potato species. Potatoes were introduced outside the Andes region four centuries ago‚ and have become an integral part of much of the world’s cuisine. It is the world’s fourth-largest food crop‚ following rice‚ wheat and maize
