Cell Biol- Genetics practical - Lab Report Example The activity of protein also varied between the fractions, with the liver particulate and lysed liver particulate showing higher levels of protein than the supernatant. The results of the experiment indicate that the majority of energy converting reactions is centred within the mitochondria, with the MDH reaction causing the highest amount of absorption, suggesting a stronger reaction. The prevalence of protein within this portion of the cell supports this hypothesis. The use of electron acceptors to measure the strength of reactions was an effective approach to determining the prevalence of each reaction, as well as their localisation within the cell. Throughout the human body, different enzymes interact with one another to form comprehensive reactions and chains of reactions that play important roles in the functioning of the human body (Schilling et al., 1999). The exact combination of enzymes and reactions that occur differ depending on the part of the body that is being considered, and the function of the cell. For example, the cells in the brain may perform some of the same functions as cells in the liver, such as cell replication, while other functions are significantly different, resulting in the use of different enzymes. The liver has a range of roles, including the maintenance of blood glucose during starvation by the activation of glycogen. It is a critical organ for survival (Salway, 2012). As well as variation in function and enzyme composition across organs and areas of the body, this also occurs within organelles present within cells. Determining what enzymes are present in different cellular components and their level of activity can be achieved through the use of cell fractionation techniques (Scnaitman and Greenawalt, 1968). One cellular component of interest is the mitochondria, which are essential organelles, involved in cell death pathways as well as the production of metabolic energy (van Loo et al.,

The Impact of Information System on Business Process Design - Research Paper Example The use of information systems also enables the company to expand and grow its operations outwards to scales that were almost unimaginable through the analog system of business design and engineering, such as globalization processes through the creation of the subsidiaries by multinational corporations. Furthermore, the organizations also benefit from the large market sphere and control brought about by the introduction of business technology and information systems within the processes of conducting business. As such, the paper considers the best methods undertaken by businesses in expanding and modernizing their operations using and adoption of technology and information systems. In fact, information systems brought about a major revolution in specific organizational sectors such as the executive and management roles, as well as, the manner and style by which people work at their organizations. This is phenomenal through the redesign processes of these business operations, and the benefits achieved through the transformation of these new company practices. A business process is a structural procedure of diverse activities, tasks, or procedures within a business in order to achieve a specific goal, or produce a certain kind of service, product, or brand for meeting a particular demand from a customer, a market, or a business client. A business process incorporates a flowchart kind of operation whereby a sequence of integrated activities operate together through a process matrix based on a varied rules provided by the data in the processes. However, there are varied versions on the definition of business processes and how they affect the operations of a business.
