U.S. and international business operations and environments Essay

U.S. and international business operations and environments - Essay Example Cultural diversity identifies one of the differences. The American domestic culture is largely homogeneous and identifies uniform behaviors and practices in business negotiations and agreements. This is however contrary to the international environment that has diversified cultures and requires extensive knowledge of the cultures for successful business initiatives. Failure to understand the different cultures disadvantages operations in the international environment as opposed to experiences United States’ domestic set up. Business operations in the Unites States majorly uses the U.S. Dollar for transactions while operations in the international environment encounters many currencies, requires currency conversion and is susceptible to losses due to variations in currency values. Business operations and environment in the United States are also subject to a homogeneous legal environment under the federal laws and variations within state laws are not very significant while oper ations and environments in international set ups are regulated by different legal systems. Similarly, moral obligations, as derived from cultures, are homogeneous in the domestic business environment but diversified in international set up. Business operations in the United States are also majorly conducted in English while the international set up involves a multilingual approach that sometimes requires translators (Dlabay, Scott and Scott, 2010). Business operations and environments in the United States are therefore different from those in the international set up with culture, currency, legal environment, language, and ethics as the major bases for the

Rate of product formation in an enzyme - catalyzed reaction Lab Report

Rate of product formation in an enzyme - catalyzed reaction - Lab Report Example Each and every protein has a specific site or substrate binding and this site remains active at specific pH, temperature and concentration of the substrate. The enzyme active site are specific for the substrates, if some other substrate comes in contact with the enzyme, there will be no ligand – receptor complex (Gurung et al., 2013).This is carried out by the ligand – receptor complex. The enzyme bound to its substrate, forming enzyme- substrate complex, which became activated. At the end of the reaction, the product is released and the same enzyme is ready to react with other substrate. The enzymes are affected by many external parameters such as pH and Temperature. The alteration of the active site occurs due to the change in pH and temperature. The protein gets denatured and loses its active site. Finally the enzyme activity is lost (Gurung et al., 2013). Catecholase is an enzyme present in plants. Catecholase catalyses oxidation of catechol. Catechol is found behind the skin of many fruits such as apples, potatoes. Catechol molecules on exposure to air, gets oxidized into benzoquinone. Benzoquinone is a brown color substance and changes the solution color to brown. Benzoquinone thus formed inhibits the growth of the micro organisms in the fruits. Catecholase oxidase catalyzes the oxidation of the aromatic group with adjacent phenol groups. This enzyme requires copper ions for the activation. The activity of the enzyme depends on temperature, pH and substrate concentration. The enzyme structure and activity is dependent on the active site and variable groups. The catecholase catalyzed reactions were tested with the given sample. Two test tubes were taken and to each of them 1 ml of potato extract was added. To the test tube named B 2ml of deionized water was added and to the test tube C 1 ml of deionized water was added. To B test
