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

AP Biology Sunday‚ October 24‚ 2010 Enzyme Lab Write-Up Purpose: To observe how an enzyme affect the speed of chemical reaction. To describe how the concentration of an enzyme affects its ability to work. Hypothesis: Depending on the concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of

The purpose is to demonstrate the role of the kidneys in the homeostatic control of extracellular fluid volume‚ plasma ionic concentrations‚ and osmolality. Three treatment groups were utilized: a Gatorade group‚ salt-loaded (access to 0.9 g/l00 ml NaCl) group‚ and a group who only had water. In this experiment the class was able to observe and analyze the changes in urine production as a means of determining the amount of salt the body gets on a day-to-day basis. Introduction: The kidneys
