Activation Energy For The Exergonic Reactions - 1624 Words

According to the graph above, the activation energy for the exergonic reactions without a catalysis enzyme is much higher opposed to the reaction with a catalysis enzyme; the free energy is constant and doesn’t change whether if there is a catalysis enzyme; the transition state differs because in an exergonic reaction without a catalysis enzyme, it takes longer for the transition state to occur and has a higher energy peak requirement while if there’s a catalysis enzyme, then the transition state occurs quicker and has a lower energy peak requirement. For the endergonic reactions, the reaction without a catalysis enzyme has a higher activation energy requirement while the reaction with the catalysis enzyme has a significantly lower†¦show more content†¦How, specifically (4 ways) do enzymes speed up reactions and why are they more appropriate than heat in living systems? a. The four ways that enzymes speed up reactions and why are they are more appropriate than heat in living systems are: active site template, active site stretch (induced fit), active site provides a microenvironment and direct participation of the active site in the chemical reaction. For example, each enzyme has its own specific active site that only allows specific types of substrates in and allows for an enzyme-substrate complex; due to the creation of an enzyme-substrate complex, a catalysis reaction is able to occur and speed up a reaction. The next enzyme mechanism is called induced fit, and it is when an enzyme stretches a substrate molecule into a different and snug-fit transition state which allows for the stressing and bending of critical chemical bonds eventually leading to a catalysis reaction. The third enzyme mechanism is its ability to provide a â€Å"microenvironment† or providing a suitable environment for a substrate to be in (acidic, neutral, etc.) and is a key step in the formation of a catalysis reaction. The last and final mechanism of an enzyme is its ability to directly participate in a chemical reaction through brief covalent bonding between the substrate and side chain of an amino acid of an enzyme, which leads to a catalysis reaction or a sped up reaction. These are all more appropriate than heat because if the

Native Americans Essay - 870 Words

Native Americans culture is unique for many ways. Living on the reservations they were in touch with nature as well as their ancestors. Native Americans are disputed in the country, diverse among tribes, culturally mixed, and recognize their own political stands (Bordewich, 1996, p. 71). These have changed over the years, but before the reconstruction of the Native Americans the people were identifiable and knew who they were. Before the Europeans came and changed their living they felt one with the land. They believe the land was not to be owned by anyone.

Even though the Native Americans see them as spiritual and done for respect the majority see it as a protest and them wanting to go to war. There have been many movements: Revitalization movement, Handsome Lake movement, Ghost Dance movement, and the Red Power movement. Even though all of the movements are important the Ghost Dance was one of the most significant to the Native America. There were two Ghost Dance movements the second was much larger. Not only did it involve the West Coast tribes, but also the Great Basin tribes. By the second movement it had gone farther east to the Plain tribes. This movement was to show how sick the Native Americans were getting by the way they were being treated. They directed the movement towards the white leaders. It blamed the European invasion and the Americans for the miserable state of affairs on the reservations and for the destruction of traditi onal Native Americans living (Nagel, 1996, p.159). This movement ended in a massacre at Wounded Knee killing several hundred men, women, and children (Simo, 1991, P. 24). Native Americans tried to step outside the boundaries of the white Americans or the majority of the nation of the time, to make them go around the nations rules.Show MoreRelatedNative American And Native Americans1137 Words   |  5 PagesNative American Displacement Long ago on the great plains, the buffalo roamed and the Native Americans lived amongst each other.

Ethical Hacking And Information Security Essay - 2390 Words

Ethical Hacking and Information Security Merriam-Webster defines Hacker as, a person who secretly gets access to a computer system in order to get information, cause damage. But what if I told you that having a hacker is necessary? Ethical Hacking is paramount to the security of our Information Technologies (IT). The task of testing your computers and network for security vulnerabilities and plugging the vulnerabilities you find before the opposition gets a chance to exploit them. Without having the ability to do what devious personnel can do inside your IT, you will never fully understand the holes in your security. It all began in the 1960s at MIT, origin of the term â€Å"hacker†, but the science dates back to 1903 to the first ever documented hacking of an electronic device. In 1932, Marian Rejewski hacked the German Enigma Machine. The Enigma machine was an electromechanical device, equipped with a 26-letter keyboard and 26 lamps, relating to the letters of the alphabet. Inside was a set of wired drums (rotors and a reflector) that jumbled the input. The Enigma used a plug-board to swap pairs of letters, and the encryption varied from one key press to the next. For two operators to communicate, both Enigma machines had to be set up in the same way. The large number of possibilities for setting the rotors and the plug-board combined to form an exponential number of configurations, and the settings were changed daily, so the machine code had to be broken each day.

Pip saves her, but she later dies from her injuries. Estella, Miss Havishams adopted daughter, whom Pip pursues romantically throughout the novel. She is secretly the daughter of Molly, Jaggerss housekeeper, and Abel Magwitch, Pips convict. Estella was given up for adoption to Miss Havisham after her mother, Molly, is tried for murder.

Characters from Pips youth * The Convict, an escapee from a prison ship, whom Pip treats kindly, and who turns out to be his benefactor, at which time his real name is revealed to be Abel Magwitch, but who is also known as Provis and Mr Campbell in parts of the story to protect his identity.

Abel Magwitch, the convicts given name, who is also Pips benefactor. * Provis, a name that Abel Magwitch uses when he returns to London, to conceal his identity. Pip also says that Provis is his uncle visiting from out of town. * Mr Campbell, a name that Abel Magwitch uses after he is discovered in London by his enemy. * Biddy, Wopsles second cousin; she runs an evening school from her home in Pips village and becomes Pips teacher.

After he realizes the error of his life choices, he returns to claim Biddy as his bride, only to find out she has married Joe Gargery. Biddy and Joe later have two children, one named after Pip whom Estella mistakes as Pips child in the original ending. Orlick was attracted to her, but his affection was unreciprocated.
