Introduction Pyrophosphatase (PPase) has been known to be a byproduct of biosynthetic reactions which is exposed to hydrolysis pyrophosphate. Pyrophosphate is an inorganic and therefore, when it exposed to reaction through hydrolysis it forms orthophosphate. It is an enzyme that is used to catalyze the process of conversion of a molecule of pyrophosphate to two phosphate ions. It can also be used in the conversion of hydrolysis of inorganic pyrophosphate to come up with orthophosphate. In short, it is a catalyst which is used in the formation of orthophosphate through the reaction of hydrolysis of inorganic pyrophosphate. The reaction of pyrophosphatese formula is P2O7-4 + H2O -> 2HPO4-2. The reaction of pyrophosphatase realizes energy and it cannot be reversed and therefore, it is capable of driving biochemical reaction to conclusion.However, the pyrophosphatase is produced in several metabolic reactions such as the activation of amino acid, reaction of synthetic products through hydrolyzing of the pyrophosphate to form a product. The phosphate produced through the reaction control several reactions which occur in biochemical. This is because the energy produced during the reaction is required for the biochemical process or reaction to occur (Pynes & Younathan$, 2012, P. 15). However, pyrophosphatase enzyme kinetics is the pathway that facilitates the reaction of pyrophosphatase through hydrolysis. Kinetic is crytalized inorganic phosphate which comes from bakers yeasts. It is applied in the reaction so that the process could faster and also to mutant the process.Materials and methodsIn order to complete the study accurate several materials were used in the lab to make sure that the lab result is accurate. The materials which were used are reagents such as pH, enzymes concentration and acids. The tubes, notebook, pens and computers where used to conduct the study. The computer or laptop was used in the final phase to record and conduct tabulation of the result. The study was conducted in the biology laboratory where all materials need could be found.ProceduresEnzyme reactionFirst, the tubes were set and then the reagents are poured inside each tube. The tubes were set with Water, pyrophosphatase 3.0 ml and enzyme pyrophosphate. The enzyme of 2.5 ml was then added to each tube containing water, pyrophosphatase and triethanolamine buffer TEA, pH. The observation was made and it was evident that after 30minutes interval the reaction of enzymes with the reagents starts. Exactly after 2 minutes the stopping agent was added to each reaction including tubes where enzyme was not placed. Immediately after 10mins the tubes were transferred to a room temperature for the color to develop. The observation was done and the reaction note for further analysis.Effect of enzymes concentration on Hydrolysis reaction The study discovered that the rate of enzymes reactions is affected by the enzyme concentration and therefore, the higher the concentration of enzyme the higher the rate of reactions. It is evident the hydrolysis reactions is higher when the concentration of enzymes is higher. The result indicates that when the rate of enzymes is 0 ml, the rate of hydrolysis reaction is 0.021 min/mL. The reaction increases as the concentration of enzymes increase along the graph. This is because when the concentration of enzyme increases the substrate concentration increases as well and therefore, the rate of reaction increases (Glatter O & Esterbauer, 2015, p. 23).Based on the result on figure2, at 0ml concentration of enzyme the substrate is not available and therefore, the reaction will occur but a product will be formed at therefore, the reaction is lower or not there. In the process of enzyme reaction a substrate is needed so that it catalysts the process of reaction. Substrate is a substance which molecules used to act upon so that it can activate its reaction. According to Glatter and Esterbauser (2015, p. 15), when reaction has less substrate the reaction the reaction is will decline, this is because there will be no substrate to react with enzyme and therefore, the reaction between substrate and enzyme will form a product hence the hydrolysis reaction will decrease. It is therefore, evident from the result above in (Fig: 2) that the higher the concentration of enzyme the more the hydrolysis reaction. It can be concluded that concentration of enzymes enhance or increases the hydrolysis reaction.Effect of pHThe result obtained indicates the pH affect the reaction and therefore, it affects the process of hydrolysis. It shows that the higher the pH, the higher the rate of hydrolysis reaction. From the reaction of pH and enzymes it is recorded that the lower the pH, the lower the rate of reaction. The result in pH reaction noted in graph in figure 3 indicates that when pH level is 4, the average rate of hydrolysis reaction is 0.02mL/min. And when the pH level increases to 10.5, the average rate of hydrolysis reaction increases to 0.041 mL/min. and therefore, it is an evident that pH level affects the rate of enzyme reaction. This is because higher level of pH causes more collision of enzymes and therefore, increases the rate of enzyme reaction. The collision of enzymes makes it possible for substrate to bind to the enzyme’s active position repeated hence increases the rate of reaction. It is therefore, that the level of pH affects the enzymes reaction hence increases or decreases the rate of hydrolysis reaction.Effect of temperature From the result obtained it is evident that temperature effect enzyme reaction. The higher the temperature the higher the average rate of reaction of the enzyme and therefore, increased increase required a higher temperature. Since the enzyme has a maximum temperature at which it works best. The temperature above the optimum the reaction of the enzyme will automatically reduce. In the graph (figure 4) the optimum temperature for the enzyme reaction is 70 degree, and after 71 degree, the enzymes become inactive and the reaction will not occur and therefore, the reaction decreases tremendously. It is because for enzyme reactions to occur temperature is needed to allow more collision to take place and therefore, it will make substrate to bind with enzymes and therefore, more reaction will take place. The more binding between substrates and enzymes, increases the reaction and therefore, the average rate of hydrolysis reactions will increase.The result obtained from experiment is consistence with expected result since, other studies and literature have showed that the rate at which the enzyme react is being affected by temperature, pH level and the concentration level of the enzyme. According to Temelli (2014, p. 24), the reaction of enzymes depends on the number of substrate inside the reaction and when the concentration of enzyme is higher substrate substance is many and therefore, it increases rate of reaction. Research has also established that the rate of chemical reaction is influenced by the enzymes and the higher the concentration of enzyme the higher the chemical reaction (Temelli, 2014, p. 23). However, the result obtained from the experiment agreed or similar with other studies which have been conducted earlier.However, the error could have been realized when reagents were being mixed, could be realized during tabulation because human can register error when doing tabulation. It is also possible to have error when the reagents or tubes were place under room temperature. Anything might have mixed with the test which cannot be identified easily. The improvement can be done to avoid any chances of making an error in the final result such monitoring the result continuously.ConclusionBased on the result obtained from the study conducted in the lab, it is evident the concentration of enzyme affect the rate of enzyme reaction. This result agrees with other studies which have been conducted by different scientists. The result of the study shows that when the concentration of enzyme is 0mlL, the rate of hydrolysis reaction is 0.02mL/min. From the result of the experiment conducted, it can be summarized that the level of concentration of enzyme influences the chemical reaction. The result of the effect of pH is evident from the result obtained.The result indicates that the lower the pH level the lower the rate of enzyme reaction. It is therefore, can be concluded that the level of pH affect the reaction of enzymes and therefore, it influences the chemical reaction. Based on the experiment conduct on effect of temperature on enzyme reaction, the result indicate that the temperature level affect the rate of enzyme reaction and the higher the temperature the higher the average rate of enzyme reaction. It can therefore, be concluded that temperature level influences the rate of chemical reaction.BibliographyGlatter O, S., & Esterbauer, S. (2015).
