Purpose: The purpose of this lab was to observe and understand the effects of changes in temperature‚ pH‚ enzyme concentration‚ and substrate concentration on the reaction rate of an enzyme-catalyzed reaction. Another purpose of the lab was to explain how environmental factors affect the rate of enzyme-catalyzed reactions. Hypothesis: I believe that if there is an increase in enzyme concentration‚ an increase in temperature‚ or an increase in pH‚ then the intensity of the reaction will

Characteristics of a dystopian society are shown throughout George Orwell’s novel 1984‚ and in the 2002 film Equilibrium directed by Kirk Wimmer. Winston Smith‚ in 1984‚ is a lower ranked member of society‚ with an outer party member job. He is watched twenty-four hours a day‚ seven days a week through telescreens set up throughout Oceania. He always finds the Party’s

Experiment No. 2: Dynamic Equilibrium and Le Chatelier’s Principle December 1‚ 2011 Final Formal Results Le Chatelier’s Principle states that “when a stress is applied to a chemical system at equilibrium‚ the equilibrium shifts in a direction that reduces the effect of stress” (Gross‚ Abenojar‚ and Tan 23). Moreover‚ it helps us “predict the direction of the shift of the equilibrium” (Silberberg 745). Silberberg also stated that there are three kinds of disturbances - concentration‚

price above the equilibrium price reduces social welfare In a free market demand and supply alone determine the price. This means that quantity of demand and quantity of supply equate at this point is where the price is set which is therefore called equilibrium price. (Griffiths‚ 2011) Figure 1 illustrates where supply and demand intersect‚ this being the Equilibrium price and Quantity

The Effect of the Changes in the Environment to the Functionality of the Enzymes Introduction a. Background In our everyday lives‚ enzymes are used in our bodies‚ and in nature around us‚ to speed up the chemical reactions happening constantly‚ which happens by lowering the amount of activation energy needed to start various reactions. The way this works is by attaching the particular substrate to the active site of the enzyme‚ where it will start to aid the chemical reaction. Then‚ the allosteric

Observation Zinc Shot: Silver color‚ some pieces are shiny while the majority is dull. Tear shaped pieces (round at base with pointed top). No odor. Zinc Granular: Silver in color‚ semi shiny‚ flaky appearance. No odor. Zinc Sheet: Sheet of metal‚ flat pieces that are about 3 inches wide & 2 inches in length & 0.02 inches in height. Each piece has a dull side and a shiny side. Silver in color‚ the dull side has a darker shade of gray. No odor. Zinc Powder: Gray very fine powder. No odor

Results Figure 1 shows that the response of the tissue increased with bath concentration of ACh (M). The logarithms of bath concentration for each response were used to form a clear sigmoidal formation‚ and thus depict a more clear relationship between concentration and response. Figure 1 shows the increasing rate of response as bath concentration increased‚ before plateauing around the highest concentrations. Responses ranged from 0.685-100%‚ while bath concentrations of ACh ranged from 2 x 10-10

Studying the Rate of Reaction of catechol oxidase and how it affects pH levels Introduction: In this lab‚ we studied the activity of an enzyme that is found in fruits and vegetables called catecholase or catechol oxidase. An enzyme is a protein molecule that is a catalyst. Catechol oxidase is the enzyme in fruits and vegetables that turns them that undesirable brownish color; also commonly referred to as bruising or bruised.
