Angiotensin-converting enzyme

1. Why is it necessary to have positive and negative controls in this experiment? It is necessary to have positive and negative controls in this experiment to see how variables are affected; therefore, without controls there would be no way to now what would normally happen with the chemical reactants. 2. Describe the movement of each substance in the dialysis bag and the beaker. The movement of glucose in the dialysis bag was that is crossed the dialysis membrane; therefore, it was found…

PURPOSE/QUESTION The question that we will answer using this laboratory report is, “How is the rate of dissolving sugar affected by changing the temperature of the water, changing the rate of stirring, and changing the size of the crystal?” The independent variable of each laboratory experiment is different, however they are all being changed to get consistent and effective results for one dependent variable. The three independent variables are the temperature of water, rate of stirring and size…

Table 1, shows the exact chemicals used to prepare silica solution, zinc acetate solution and zinc nitrate solution. For the zinc acetate, adding 2-propanol to the hydrated zinc acetate will result in a white solution with some precipitations of zinc acetate in the bottom of the beaker, then by adding 2.1 grams of diethanolamine, ratio is 1:1, the solution will be transparent; due to the effect of diethanolamine which increases the pH of the solution, make it basic. Dissolving zinc nitrate in…

The purpose of this experiment is to quantify the air quality and emissions of a local Nacogdoches Tadarida brasiliensis, Brazilian Free-Tailed bat colony. Concentration of ammonia, particulate matter, fungi and bacteria were measured to assess air quality. The guano at the base of the garage was also analyzed for nitrogen and carbon content. The colony briefly lived in the north end of parking garage on East College Street and Raguet Avenue until its untimely removal. The colony could be seen…

Catalysts and Inhibitors work by providing an alternative reaction pathway for the breaking and remaking of bonds in chemical reactions, changing the speed of the reaction. They are neither consumed in the reaction. Rather, they alter the amount of activation energy required. Different reactions require different catalysts, as well as different reactions require different inhibitors. The reaction energy path controls the speed of the reaction. The molecules follow the path of least resistance,…

Objective: To understand the function of an enzyme when it undergoes different conditions such as temperature, PH, and concentration of the enzyme. Introduction: In our lab “Enzyme Action” we were testing the enzyme reaction with different substrates. In our lab we tested 3 different enzymes and substrates to find out when they are at the highest potential. Enzymes are necessary for life because they keep our bodies chemical reactions at a normal pace. Enzymes have the ability to keep a human…

These claims are to say the least, unbalanced truths. By the end of this discussion it would have become obvious that there is no basis for undue generalizations in the management of cancer. There still remains the need for expert judgement in formulating a cancer treatment protocol. BEFORE CANCER First, let me state that the human body will literally rust away like a nail left under the rain over time without inbuilt natural protective mechanisms. To prevent rust or oxidation, most…

Purpose: The purpose of the lab was to identify a powder based on its physical and chemical properties. Materials & Apparatus: -eye protection -well plate -pipette -small toothpick/ paper clip for stirring -6 white powders: icing sugar, cornstarch, Aspirin powder, baking powder, mystery powder -test solutions in dropper bottles: water, universal indicator, vinegar, iodine solution Safety notes: Aspirin Powder- in case of contact with skin, wash with soap and water. Universal indicator- toxic…

Stoichiometry is known as the quantitative relationship between various products and reactants in a chemical reaction. There are many ways one can stoichiometry in his/her advantage. If you start off with a known amount of reactant, stoichiometry can definitely be used to make a prediction to the amounts of the future product that will be formed. And in the other side, if you has a desired amount of product want, you can use stoichiometry to predict of on how much reactant you will need to…

10. Describe the physiological roles of the different subclasses of immunoglobulins. How do the structures of these compounds relate to the function of the different classes of immunoglobulins (50 Marks?) There are four different subclasses of immunoglobulins which are IgM, IgG, IgA and the IgE. Each subclass has its physiological role in relation to its structure. The m immunoglobulin (IgM) is the first primary subclass which is produced due to primary response of the immune system. IgM is the…
