Isolation and Investigation of Catalase Lab Report

Isolation and Investigation of Catalase - Lab Report Example The enzymes are also applicable in various fields like medical applications and industrial applications. This report seeks to examine the effects of pH, temperature on the action of catalase enzyme. The change in pH is the degree in which an environment changes either from acidity to alkalinity or from alkalinity to acidity. When the environment becomes so acidic, it may completely inhibit enzymes from facilitating the reactions. The change in pH has an impact on the repulsive forced and the attractive forces and may completely change the shape and the size of the active sites such that the substrate molecules may fail to fit (Siow, 2009). This inhibits the chemical changes from taking place. The basic groups such as the nitrogen are protonated in an acidic condition and they are deprotonated in an environment that is basic and makes alterations in the electrical attractions that exists between the polar components. Catalase enzyme has an optimum pH value that it operates, beyond which it is inhibited. (Enger, Ross & Bailey, 2012).   When catalase is added to the hydrogen peroxide, a reaction occurs producing oxygen gas. The experiment seeks to investigate the temperature effect on the enzymatic actions by measuring the level of oxygen produced within a given period of time (Vetiska, 2004).   It is noted that enzymes work best between pH values ranging from 7 to 10 as illustrated in the table above. The rate of reaction increases as the pH increases from 5 to 7, which is a neutral point. As the pH continues to increase from 10 to 12, the rate of reaction starts to decrease and the volume of foam produced decreases. It was seen that as the ph changes from the optimum to alkaline range, the catalase enzymes lose the hydrogen ions (Crofts, 2013).  Independent variable is the temperature of the environment, dependable variables is the catalase enzyme, and Constant variables are the time used and the amount of catalase used.

Report on Media Legal Issues (Digital Movie Revolution) - Research Paper Example In fact, a good number could not make independent films until they attended a certain school to acquire the equipment or they grew up with the set. In the past, most people faced challenges until they went to Hollywood to land a job on a movie set of the needed equipment. Conversely, today in as much as there is a lot of networking and dues paying to venture in the movie business, the internet radically has altered what looks like and more especially change has been in the accessibility (Silver, 2003). It has simplified almost for everyone to do video project and have seen as wished. This is possible since the advent of less expensive digital technology. Websites like Vimeo and YouTube have played a role in allowing anyone with camera to post a video. The computers made it possible to edit enabling anyone tweak their projects or other peoples projects to make them even look much better. As a result, many aspiring filmmakers, who would otherwise have lacked the resources to be seen, can now go public on their own. The movie industry probably will soon take the lead from the independent colleagues that have made significant steps towards digital filmmaking (Prince, 2012). This facilitates the digital revolution found in every setting of the movie industry. Indeed, this is a landmark development concerning the evolution in the field of entertainment. Allowing customers to be able to access and even own movies digitally by downloading via broadband internet connections has allowed them more power to be entertained to their satisfaction. Unfortunately, in the period when the movie industry was in aid of embracing digital distribution onl y a handful of the companies already had started the trend which did not include the video clip download sites (Silver, 2003). Already video streaming and the download sites have been able to provide content including the
