System and Operation Management - Assignment Example This company started with photocopying services and then moved to printing services, which motivate its development until currently. The performance of the selling points has been up to date although with some few setback here and there. This paper highlights the setbacks and provides insights on the areas where the company has shown good performance. It also looks deeply at some of the problems the company is experiencing and provides strategy for making changes in the organization. First, the history of the organization tells much more about the company structure and how it developed from a very low status to become a reckoned organization in the entire Europe region. Introduction History of the Company Atokowa is an organization that deals within the office supply industry within the Australian region. The company sells several items that are used in offices. For instance, the organization deals with selling office furniture, printing and paper. Initially they sold printed fliers, business cards among other office equipments. The company started from a humble background when Lachlan bought his first photocopying Xerox 914 machine in Sydney and started photocopying services in his garage in the year 1964 (Gomez-Mejia, David and Robert 2008). The organization started expanding in through printing and reproducing several copies for different companies. Atokowa tremendously grew in 1970 when Lachlan bought a retail outlet thus expanding his services to include printing services. This enabled him to develop a high reputation in service delivery providing the organization a better environment for growth and development. Additionally, the company gained a good picture when the owner decided to make it as a one point for selling and buying and further coming up with decisions for identifying and setting up new shops in different areas of Europe at large. The organization got its name from the original owner as he felt that this was the right name for it (Kotter, Joh n & Dan 2002). Lachlin wanted to retire early from business activities and let eldest son Jonathan Atokowa run the business in the year 1983 (Gomez-Mejia, David and Robert 2008). It is during this period that Jonathan Atokowa became more focused on technological improvement of the company. He introduced the selling of Commodore 64 together with IBN PC 5100 that was the highest technology during that period. Jonathan has continually followed his father’s footsteps for developing the organization through involving in selling of various technological equipments in its different selling points in the Australia. Regional outlets that sell under Atokowa name are found in areas like Canberra, Adelaide, Newcastle and Brisbane regions. The picture below indicates all retail regions that enjoy services from the organization. Purpose of the report Business operations require that customers get their services to the fullest. This is quite challenging in some cases where the organization has many outlets that serve many customers. The company that applauds best services for its customers has the

Aerobic Cellular Respiration in Isolated Mitochondria of Lima Bean Lab Report

Aerobic Cellular Respiration in Isolated Mitochondria of Lima Bean Seeds - Lab Report Example During aerobic respiration, oxygen in the air is used as the final electron receptor which subsequently gets reduced to water. Energy is generated during this process in the form of a high energy molecule, adenosine triphosphate (ATP). This is a complex process involving a series of reactions that use many chemicals and enzymes. Glucose is the most preferred source for cellular respiration and as reported by Rich (2003), it release high energy (29-30 ATP molecules per glucose molecule) during aerobic respiration. Aerobic respiration consists of 3 major steps as glycolysis, Krebs cycle (Citric acid cycle) and electron transport chain. During glycolysis, pyruvate is produced by glucose which is converted to a 2C molecule, acetyl-CoA. Acetyl-CoA combines with the 4C oxaloacetate (last product of the previous Krebs cycle) to produce citrate which is a very high energy source. During the Krebs cycle, citrate is consumed in an 8-step process to release this energy (electrons). Here, the co enzymes FAD (flavin adenine dinucleotide) and NAD+ (nicotinamide adenine dinucleotide) gets reduced to produce a small quantity of carbon dioxide and ATP. Therefore, hydrogen electrons coming from glucose will reduce FAD and NAD+ to FADH2 and NADH + H+ respectively. These electrons then enter the electron transport chain to get oxidized and produce ATP. ... This reaction is catalyzed by the enzyme succinic dehydrogenase using FAD as co-enzyme. In this reaction, 2 hydrogen atoms are removed from succinate and transfer to FAD thereby reducing it to FADH2. DPIP (2, 6-dichloro-phenol-indophenol) blue dye can act as a hydrogen molecule acceptor instead of FAD during this reaction. When DPIP receive hydrogen from succinate, blue color get decolorized. Thus the DPIP color change from blue to colorless is an indication of the level of enzyme activity in the mitochondria which can be measured and recorded with a spectrophotometer. The Krebs cycle is influenced by competitive and noncompetitive inhibitors. Competitive inhibitors compete with the substrate to bind to the active site of the enzyme and this can be overcome by providing more quantity of substrate molecules. Conversely, noncompetitive inhibitors such as metal ions (copper, Cu2+ and mercury, Hg2+) will deactivate the enzyme thereby making it impossible to return back to the reaction. T herefore, the reaction cannot be reactivated by incorporation of more substrate. In the succinate-to-fumarate reaction of the Krebs cycle, Malonate act as a competitive inhibitor on succinate molecule. Molecule shape of malonate is similar to succinate molecule and thus it obstructs the conversion reaction of succinate to fumarate by binding to active site of the enzyme succinate dehydrogenase. However, as described in Zeevalk, Derr-Yellin and Nicklas (1995) it will not react further and result in the termination of the reaction. Therefore FAD will not reduce to FADH2 and fumarate will not be produced, thus arresting the Krebs cycle. As malonate is a competitive inhibitor, the reaction can be
