Enzymes - science lab Report ExampleAs stated by Onteh et al (2005), most biochemical replys would be very(prenominal) slow without enzymes since enzymes growth the rate of biochemical reactions by thousands times. It is therefore important to study the environmental factors pH and temperature and how they would affect particularized enzymes.There are three characteristics of enzymes that make them function as catalysts. First enzymes increase the rate of biochemical reaction, second, they are specific to a substrate and thirdly they can be modulate to increase or reduce rate of biochemical reaction. Studies have confirmed that enzymatic activities are unnatural by certain factors such as enzyme concentration, pH, and temperature as well as substrate concentration. According to (), all(prenominal) these factors except substrate concentration have the effect of modifying the specificity nature of the enzyme there by making it at variance(p) with the substrate. Moreover enzyme s act as catalysts because they exhibit three dimensional protein structures. As stated by Onteh et al (2005), this structure is particularly sensitive to changes in salts, pH and temperature thus a slight changes in temperatures of reaction can significantly change the rte of reaction while extreme temperatures can irreversibly alter the two the three dimensional structure of the enzyme thus making it impossible to catalyze a reaction.The enzymatic activeness is based on the fact that enzymes are made up of certain active sites that are specific to the substrates active sites. As stated by Onteh et al (2005), it is on this active sites that enzymes tie to a given substrate in a geometrical fashion after which substrate undergo its inherent reaction at a much faster rate. This mode of enzymatic action is referred to as lock and key. It is important to note that enzyme does not actually react with a substrate, but brings and aligns the substrate in order for it to react with othe r substances. Enzymes therefore have
