Enzymes - Lab Report ExampleAs stated by Onteh et al (2005), most biochemical re functionions would be very slow without enzymes since enzymes append the rate of biochemical contradictions by thousands times. It is therefore important to study the environmental factors pH and temperature and how they would affect specific enzymes.There are three characteristics of enzymes that make them modus operandi as catalysts. First enzymes increase the rate of biochemical reaction, second, they are specific to a substrate and thirdly they can be regulated to increase or reduce rate of biochemical reaction. Studies have confirmed that enzymatic activities are affected by certain(p) factors such as enzyme concentration, pH, and temperature as well as substrate concentration. According to (), all these factors except substrate concentration have the effect of modifying the specificity nature of the enzyme there by making it incompatible with the substrate. Moreover enzymes act as catalysts beca use 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 both the three dimensional structure of the enzyme thus making it impossible to catalyze a reaction.The enzymatic activity 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 bind to a prone substrate in a geometrical fashion after which substrate undergo its inherent reaction at a much faster rate. This method 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 other substances. Enzymes t herefore have
