Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially

The results of coal mining are destroying the environment. Regulators are trying their best to get coal mining companies to put money aside to clean up the devastating mess they have made‚ so that the tax payers do not have an outrageous $1 billion bill to pay. Many companies claim that their cleanup plans are well funded‚ but many believe this to be false because the demand for coal is low and many companies still remain bankrupt. The biggest problem is with the business Alpha Natural Resources

The Effects of varying p-Nitrophenyl Phosphate concentrations on Alkaline Phosphatase Activity Nathan Overholt Louis Settembrino March 5‚ 2002 Abstract: The enzyme Alkaline Phosphatase was set up in solutions of varying p-nitrophenyl phosphate concentrations. A fixed time assay was used to find the Michaelis constant and Vmax. All solutions were incubated at 30 C° for 30 mins. Absorbances were measured at 405 nm‚ and the Km was found to be 0.002 M (pNPP) and the Vmax to be 0.433 A/min. Introduction:

Lab Report (Effect of concentration on enzyme activity) Biology Noor Alawadhi 11- KC Introduction: An Enzyme is a protein‚ which is capable of starting a chemical reaction‚ which involves the formation or breakage of chemical bonds. A substrate is the surface or material on or from which an organism lives‚ grows‚ or obtains its nourishment. In this case it is hydrogen peroxide. This lab report will be explaining the experiment held to understand the effects of the changes in the amount of

Effects of Changes in Physical Properties on Enzyme Activity By Alex Hoffmann First Individual Lab Report Wednesday 7:30-10:15pm 10/24/12 Meghan Duell Abstract The goal of this lab was to determine the effects of certain physical properties on enzyme activity. Enzyme activity was measured by the height of the bubbles that appeared after the enzyme was added which are proportional to the rate of the reaction when time is constant. The fact that enzyme activity is affected by physical

Delivering Learning and Development Activities: Customer Service Presentation Review 3.1 Feedback When planning and presenting my training session a factor that influenced it was my own knowledge of customer service training. Like others I taught‚ I had already gone through the process at work. I learnt the basic principles and adapted this in the workplace to provide excellent customer service.

In “Arizona and New Mexico”‚ a text written by Aldo Leopold‚ he talks about how man has developed the untouched land in the White Mountains of Arizona and killed animals in New Mexico‚ and now the lands are trodden on and it is not at all the way it used to be. In “A Very Warm Mountain”‚ a text written by Ursula K. Le Guin‚ she writes about how the earth is destroying itself because of what the human s have already done to the land‚ by the eruption of Mt.
