It is an energy source for biochemical reactions such as muscle contraction‚ active transport‚ molecular synthesis‚ and in fireflies‚ also known as lightening bugs‚ bioluminescence (Biology Book). Bioluminescence is the process in which living organisms convert chemical energy into light (Branchini‚ 2008). In the fireflies case the reaction involves the enzyme luciferase which lights up a lantern-like mechanism under the tip the wings and

    It was hypothesized that if the animal was larger‚ then it would have larger hemoglobin. It was thought that larger mammals would need more oxygen-rich hemoglobin to support healthy function. This lab did not support this hypothesis. The results in table 1 displayed that the hemoglobin of all mammalian samples traveled about the same distance. This trend can be seen in graph 1 as the mammalian hemoglobin samples migrated the same distance. Because the proteins traveled around the same distance it

Many enzymes are essential for life and reactions would not happen rapidly to maintain life with the help of enzymes. Specific enzymes lower the activation energy for specific reactions and shapes. Activation energy is required to start a chemical reaction. This occurs when energy is added to reactants. Amino acid chains are

    Lauren Sullivan Plants Imperfections Abstract The purpose of this experiment was to plant different crosses and observe the different phenotypic ratios the plants present. The procedure of this experiment was plant six different crosses and water them correctly so that we could observe the different phenotypes and compare them to Mendel’s proposed ratios. Mendel‚ who had studied peas‚ did a similar experiment and came up with specific ratios that a monohybrid and dihybrid cross should show. His

    acetylsalicylic acid by esterification. Introduction: A pleasant‚ often fruity‚ odor is characteristic of some of the simpler esters. Ethyl butyrate smells similar to pineapples‚ the odor of n-propyl acetate is reminiscent of pears and isopentyl acetate has a strong banana fragrance. Esters are derivatives of the carboxylic acids and contain the following functional group: The synthesis of an ester can be accomplished in one of several ways. An esterification occurs when an alcohol and a carboxylic acid are
