The Characteristics of Enzymes in the Body Essay

The Characteristics of Enzymes in the Body - Essay Example The essay "The Characteristics of Enzymes in the Body" talks about the organic compounds that catalyze biochemical reactions. As they are catalysts, they are not consumed in the reaction but instead, facilitate a faster reaction rate. Enzymes in the body are mostly globular proteins or conjugated proteins. While almost all the known enzymes are proteins, enzymes such as RNase made of ribonucleic acids have also been discovered. Enzymes undergo denaturation upon slight variations in temperature and pH, as well as in the presence of chemicals that are protein denaturants. Enzymes work best at a particular optimum temperature and pH specific to that enzyme. Denaturation of an enzyme occurs when the shape of the enzyme is altered by changes in temperature and pH, both of which affect the protein structure of the enzyme. Denaturation results in the deactivation or loss of enzymatic function of an enzyme. Above and below the optimum temperature and pH, the activity of the enzyme either slo ws down or comes to a halt. Certain chemicals called inhibitors also affect the functioning of an enzyme. Inhibitors deactivate enzymes in several ways. They may bind to the active site of an enzyme and alter its shape, resulting in an inhibition of its catalytic activity. The catalytic activity of enzymes is not only affected by the pH and temperature, but also the concentration of the substrate and the product. As the concentration of the substrate increases, the enzymatic activity also increases up to certain substrate concentration.

Sopholces plays often seem to support the idea of democracy. What specific statements and events in Antigone make this true If you disagree then show how antigone is actually undemocratic - Essay Example All democratic acts are regarded as tyranny against the state and thus, punishable. The first instance is made in reference to the burial of the two brothers of Antigone. Eteocles who was not honorable by Greek’s standards, was given a respectful burial but Polyneices, who was considered an honorable man was denied the right to a respectful burial (Butler, 2000). The play begins at this instance when Antigone is pleading with her sister Ismene to help her bury their brother regardless of Creon’s orders. Ismene refused to help as she is afraid of the law as declared by Creon. She confesses to her sister that, â€Å"I yield to those who have authority† (line 67). She states that the divine law that allows her to give a befitting burial and respect the dead was being taken away from her and she strongly decided to respect the law of the gods as they were conflicting with those of Creon. In lines 453-55, she says, Even though Antigone is aware that being disobeying Creon’s orders will cost her life, she cannot risk disobeying the gods. She says that she is not afraid of Creon’s wrath than she is of â€Å"the gods’ tribunal† (458). There is no democracy in Antigone as the whole state is in uproar over the wicked reign of Creon as king. He has become very unpopular and people are just tired of him, even his son, Haemon who he has always considered very obedient has resorted to mocking him. Creon is not even moved when Teresias approaches him to tell him what people in town are saying about him. Creon believes that the state is supreme than all the people in Thebes and as a ruler, he makes the decisions for the benefit of the state as his will sovereign. In line 188-190, he says, Democracy means that the rule doesn’t discriminate between genders but in Antigone, women are not given a chance before men (Ruthann, 2007). When Antigone brothers died, Creon took the crown because he was a male
