The Pathway Of Cancer Cells Essay - 1687 Words

Cancer cells are characterized by unlimited cell growth, inefficient apoptosis and excessive anabolism. The process of becoming cancer cells includes gene activation, micro-environmental changes and metabolic reprogramming. All of which compound upon one another and lead the cancer cells to continue with their overwhelming growth and activity. Malignant cancer cells invade and destroy organ infrastructure and replace it with disorganized and damaging cells. (1) The metabolic preference of cancer cells is wide ranging with cervical and glioma cells maintaining a normal oxidative phosphorylation and others exhibiting the switch to glycolysis. (2) This metabolic switch exhibits the adaptation to environmental changes and the tumor’s energy needs and activity. Overall, the carcinogenic process that defines each malignant tumor determines the metabolic profile of the cells. For the purpose of examining the metabolic switch, this paper will focus primarily on the Warburg principle w ith only slight examination of other cancer cell metabolic profiles. The Typical Cell Metabolism In a typical cell, the mitochondria works to provide the cell with adequate energy (in the form of ATP) in a well organized system. This system takes the glucose from the body and through glycolysis breaks it down to pyruvate, releasing 2 ATP. The products of glycolysis then enter the mitochondria, and are decarboxylated and attached to coA. Acetyl-coA can then enter the Krebs’s cycle. The Krebs cycle isShow MoreRelatedBiological Chemical Pathways And Its Effect On Cancer Cells Essay1516 Words   |  7 PagesA cancerous cell must adapt to various biological chemical pathways and modify itself to impose its malignant behavior not only in humans but as well as in other species.

The Causes Of The Salem Witch Trials Of 1692 - 700 Words

Salem Witch Trials DBQ How would you feel if your life was ruined just because you were considered unfit for society? This is exactly what was going on during the Salem Witch Trials of 1692. Prior to the trials, there were witch hunts that caused global unease mainly to Protestant societies. King Philip’s War also contributed to this unease by pushing people from the east coast and into Puritan towns. These towns had misogynistic male leadership, depriving many people of humanity because they had to live under unrealistic expectations. This leads to the question of what led to the mass destruction of faith, hope, and trust in the town of Salem, Massachusetts. Factors that motivated the Salem Witch Trials of 1692 were the†¦show more content†¦From 1675-1678, King Philip’s War pushed a variety of people into Salem which caused a division between the east and the west. The east wanted to join a neighboring city while the west wanted nothing to do with other people and the rest of the world. Because of this, a pattern began to form where the west was made up of mainly accusers and the east was made up of those accused of witchcraft (Doc F). Because of this pattern, it can be assumed that in Ann Putnam’s Deposition, Ann Putnam came from the west while the minister came from the east, considering the fact that Putnam was the accuser and the minister was the accused (Doc C). Finally, the Salem Witch Trials of 1692 was influenced by the fear of the devil. Back in Europe, global witch hunts were occurring. The idea of witches was then imprinted into the minds of the Puritans. This causes men to believe that women would have sex with the devil and because they had sex with the devil they were bewitched (Doc D). Because of this, if you were accused during the Trials, the only way to save yourself was to confess guilt (Doc B). That was how freaked out they were! So, it is easy to assume that the fear of the devil was a key influence of the Sa lem Witch Trials. Similar to the Salem Witch Trials of 1692, McCarthyism struck fear into the lives of many. This fear could tempt you into convicting someone who was a friend or even a close family member.

The market was primarily split between low-en and high-end retailers. Low-end retailers primarily focused on offering a wide array of merchandise including furniture on the basis of low prices. Aside from tight margins as part of a low-pricing strategy, there were also several â€Å"small-store retailers† targeting college students and other consumers with constricted budgets. We will write a custom essay sample on Ikea Case or any similar topic only for you Order Now Most of these stores were inconsistent with the environment ND displays portrayed, further contributing to poor inventory management practices and below-par customer service. On the other hand, high-end retailers carried either single brands or multiple brands as part of their product portfolio. Most high-end retailers employed expensive sales executives and focused more on offering value-added services including (but not limited to): measurement and product selection, customizable designs for complete makeovers, product delivery and installation, high number of SKU stemming from a base product, and even relocation of old furniture. Quality and service was the basis or these types of sellers, constantly reminding customers that their products would last a lifetime and that going through the installation hassle could easily be avoided. 2.

The main disadvantages of KEA are centered on lower-quality furniture that doses ‘t last as long as other high-end more expensive products. Also, KEA furniture is not suitable for people who plan on moving or relocating as the pieces that make a perfect example of what W. Chain Kim and Rene ©e Unbroken coined a â€Å"Blue Ocean† company. The company’s target market is considered to be niche but at the same time oriented at covering the masses and being high-volume, low-price retailers. The customer experience is unique and cannot be easily copied by other competitors. Sticking to Scandinavian-styled furniture helps distinguish KEA from traditional furniture stores while at the same time being distinctive and predictable. Blue Ocean companies such as KEA employ Continuous Improvement practices that allow for ewe styles and designs of furniture to be made available while on the lookout for cost reductions and price saving opportunities for consumers. 5. In order for KEA to continue and sustain its growth strategy and high success worldwide they have to place special emphasis to the following recommendations: a. Expand the customer base outside of established markets such as Europe and North America and target emerging economies that are also looking for inexpensive, practical and stylish ways of equipping their homes and offices. . Offer complimentary assistance for assembling furniture at an additional cost in order to attract higher-end customers who do not want to partake in the tedious task but are willing to pay a premium for the service. Specialized carpenters and contractors should be carefully selected and trained according to company standards. This allows for furniture to last longer and surv ive relocation needs. C.
