Result and Discussion The concentration of serum alanine aminotransferase (ALT)(IU/L), aspartate amino-transferase (AST)( IU/L), Alkaline Phosphatase (ALP)(U/L), Serum creatinine (mg/dl), Serum albumin concentration (g\dl), Serum urea concentration (mg/dl) in all subjects were clarified in the table and figure (1). Depending on the result in the table , a significant (P0.05) differences in mean values of serum urea concentration in all Volunteers. The liver is the most…

The table below shows what colour the solution has turned after Amylase solution and Benedict’s solution has been added to Starch solution at different temperatures. The tests were completed three times each temperature to find an average. This graph resembles the results from the table above. Making it obvious to observe the unexpected results as the temperatures 2, 20 and 27 remained blue then 37 degrees changed to green and 60 degrees changed to orange. This experiment was carried out to…

Potato Bubbles Introduction Our driving question for this lab was “How do changes in temperature and pH levels affect enzyme activity?” Throughout the duration of this lab, we explored enzymes and how environmental factors like pH and temperature affected enzyme activity. Enzymes are proteins that speed up chemical reactions. For this particular experiment, we studied the enzyme catalase, which is found in potatoes. Catalase reacts with hydrogen peroxide to break it down into its water and…

Enzymes are protein molecules that significantly speed up the rate of virtually all of the chemical reactions that take place within the cell. In the following lab was to examine an enzyme that is found in pineapples. That enzyme is bromelain its breaks down protein into their protein into their amino acid by a process of hydrolysis. They are found in tropical areas like Hawaii, Thailand, and Brazil. For the first experiment the hypothesis was that the when gelatin was added to the water, fresh…

Studying the reaction of the enzyme catalase in different temperatures The purpose of this experiment was to measure the speed and the effectiveness of the enzyme catalase. The enzyme catalase purpose is to break down harmful substances and turn them into oxygen and water. The substance in this environment was hydrogen peroxide, and the study was to see how well the chicken liver would work if it was in a boiled environment, room temperature environment, an acid immersed environment and a basic…

Enzymes are proteins that act as catalysts and help chemical reactions occur everywhere in life and throughout body. A catalyst is a specific type of protein that increases the rate of a chemical reaction. In an enzyme reaction, the substance that the enzyme acts upon is called the substrate. The enzyme has a special area called the active site, which is a particular point in the substrate at which a reaction occurs. The active site has specific shapes that match up with the enzymes to cause the…

Results and Discussion Reactions are never ending and always occurring in organisms, making them essential for our functioning. Enzymes are catalysts that are used to speed up these reactions. If you take for example if a person was trying to get from Point A to Point B, there are two routes; one route where you have to go over a steep hill, which would take additional time or the other route is to go around the hill and get to Point B using less time. This example is an illustration of…

Liver Lab By: Jonah Stillman Background Information: Catalase enzymes are inside of nearly every living organism that is exposed to oxygen. Some examples of catalase enzymes are bacteria, plants, and animals. The main job of a catalase enzyme is to catalyze the decomposition of hydrogen peroxide to water and oxygen. When an enzyme is exposed to hydrogen peroxide or certain other chemicals it is prone to react. Catalase enzyme reactions also depend on the temperature they are exposed to. As…

Background Research Enzymes are proteins that act as biological catalysts. A catalyst can be defined as a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Enzymes are essential due to the fact that virtually every metabolic reaction which takes place within a living organism is catalyzed by an enzyme. This is because organisms catalyze the chemical reactions that would otherwise not be able to progress under typical physiological…

Our initial investigation of the asymmetric Mannich reaction of indole 2a with phenyl α-amidosulfone 3a is summarized in Table 1. The effect of catalyst structure on the reaction outcome was first investigated at 10 mol% catalyst loading in toluene (Table 1, Entries 1–5). As we expected, based on our knowledge of the catalytic performance of chiral oligoEG 1,[7] the ether chain length (Entries 1–3) as well as suitable acidity of the phenolic protons (Entry 2 vs. Entries 4 and 5) are critical for…
