Enzymes:catalysts Of Life

p 6 ENZYMES : CATALYSTS OF LIFE I . INTRODUCTIONBiological organisms inherently bear with several biochemical substance processes These replys progress at a position pace mainly depending on the requirements of the living organism . Enzymes ar protein molecules that play a major role in the proper functioning of different organs of an organism . Enzymes generally swear out as catalysts to unique(predicate) chemical reactions , wherein these proteins influence the speed of a chemical reaction without experiencing the risk of being utilized until its forepart is exhausted . Enzyme proteins are structurally organized to follow a three-dimensional conformation which facilitates the correct interactions with otherwise types of proteins at its specific mobile place These proteins also consist of specific amino acid sequences that have earlier been determined by its forerunner DNA sequence coded by the nucleus of the cell . The amino acid sequences dictate the specific action and activity that separately enzyme can perform , resulting in unique enzyme specific reactions in the body of a biological organism . The active site of an enzyme also carries a specific charge that is strongly associated with the mastery of the interaction with other molecules or ions . When an enzyme protein directly interacts with its particular substrate , the enzyme is activated , hence the energy requirement to proceed with the chemical reaction is lowered , and in turn , the chemical reaction proceeds faster than its initial speedThe capabilities of an enzyme are influenced by remote factors such as temperature , pH and the presence of ions , cofactors , coenzymes and inhibitors . These factors induce a change in the shape or charge of an enzyme s active site , which then results in a change in the rate of the chemical reaction . In addition , an perfect increase in temperature can destroy a protein enzyme , description it inactivated or denatured , and its physiological shape ruined .

at that place are also certain enzymes that could not perform at its optimal setting when a specific cofactor or coenzyme is not present . Metal ions facilitate the transfer of ions , such as reduction and oxidation reactions , among proteins . Inhibitors are molecules that interact with enzymes by cover version to the enzyme s active site thus preventing the enzyme to interact with any other molecule for further interaction II .MATERIALS AND METHODS A . geological formation and Detection of BenzoquiThe following test subway systems were labeled and filledTest metro 1 : 2 ml potato evince with catechol oxidase 2 ml catechol solutionTest tube 2 : 2 ml potato extract with catechol oxidase 2ml dH2OTest tube 3 : 2ml catechol solution 2 ml dH2OThe food color of the solutions in each test tube was noted . to each one test tube was placed in a40 ?C body of water bath . The color of the solutions in each test tube was taken note after 10 minutes incubation in the water bath . The color was rated according to an fervency scale (0 - 5 , wherein 0 clear and 5 downcast brown B .
