Immunology Assignment #1 Terra MacDonald October 16th, 2013 1) The cross-matching procedure by which we determine whether the donor and recipient are compatible involves a hemagglutination reaction. Red blood cells have antigens on their surface and if the blood of the transfusion recipient does not have the same “type” of antigens on their red blood cells, the recipient will produce antibodies against the donor’s red blood cells which will cross-link with the antigens, causing agglutination

given time. Enzymes have extremely interesting properties that make them little chemical-reaction machines. The purpose of an enzyme in a cell is to allow the cell to carry out chemical reactions very quickly. These reactions allow the cell to build things or take things apart as needed. This is how a cell grows and reproduces. At the most basic level, a cell is really a little bag full of chemical reactions that are made possible by enzymes! Enzymes are made from amino acids, and they are proteins

which must be controlled: carbon dioxide, urea, ions, sugar, water and temperature. We need to remove waste products from the body to keep it working, as waste products can be poisonous to the body. If they are not removed then it can stop chemical reactions from happening and cells can be damaged. Carbon dioxide is a waste product that needs to be removed to keep the body from becoming ill. However, extra carbon dioxide must be removed; otherwise the body becomes too acidic. It is mainly lose in the

physical and chemical properties of copper by cycling copper via several chemical reactions; those reactions being, Oxidation Reduction, Acid-Base and Oxidation-Reduction and Single Displacement Reduction. Lastly, while performing a series of chemical processes, the mass of copper recovered should equal the original mass of copper from the beginning. II. Data (Experimental Observations) Part A: Oxidation Reduction Reaction The weight of the copper starting material was 0.107g. After I weighted the

also the percent purity of a sample provided. By definition, Stoichiometry is the quantitative relationship amongst elements in a compound to reactant ratio during a chemical reaction. Potassium chlorate (KClO₃), like many other oxygen composing compounds, is decomposed well by heat. Essentially there is an endothermic reaction that by the aid of a catalyst and heat will produce potassium chloride and oxygen. This equation looks as follows: KClO₃sMnO₂heat2KCls+3O₂(g) This process can happen without

States of Matter Gases, liquids and solids are all made up of microscopic particles, but the behaviors of these particles differ in the three phases. The following figure illustrates the microscopic differences. | | | Microscopic view of a gas. | Microscopic view of a liquid. | Microscopic view of a solid. | Note that: * Particles in a: * gas are well separated with no regular arrangement. * liquid are close together with no regular arrangement. * solid are tightly

when describing and explaining how the body systems are linked to energy metabolism. The meaning of metabolism is the chemical process or reaction that takes place within a living organism in order to maintain life. Some of the chemical reactions require breaking down molecules while at the same time releasing energy- this is the definition of the catabolic reactions. Instead of breaking down molecules the process of anabolism is to build intricate molecules from simple substances by using energy which

Problem Set Chapter 12 Solutions February 12, 2013 12.37 What product(s) would you expect from the reaction of 1-methylcyclohexene with NBS? First step is to form an allylic radical; however, you have two different allylic protons that can be abstracted. Once you form those, bromination at those positions gives products 1 and 2. Each of those allylic radicals can also undergo resonance stabilization to delocalize the radical. Bromination at the other side of the double bond then gives products
