Effects of Enzyme Rate by Variables of Enzyme Concentration, Substrate Concentraion, Temperature and pH

Abstract This study was undertaken to determine the effects of different environments poignant the yard of reception, PNPP (p-nitrophenyl phosphate) + H20 ? PNP (p-nitrophenol) + H3P04. This answer is catalyzed by the enzyme phosphatase. Different environments produced different reaction grade as environmental factors affect the readiness of phosphatase. This is because environmental factors depose deviate the tertiary structure of phosphatase, which alters its active spot, and on that pointof changes its efficiency to catalyze the reaction. We measured the rate of reaction, by using a chromogenic substrate, PNPP, and a spectrometer to determine the amount of return produced in 15 min and also using our dominion sophisticate created of known PNP densitys and absorbencies. The optimal conditions for phosphatase which produced the highest rate of reactions were pH of 5 and a temperature of 50ºC. We also discovered that change wander the concentration of phosph atase give increase the rate of reaction irrespective at what our sign concentration of phosphatase is. However, by increasing PNPP, the substrate, there are material increases in the rate of reaction when the sign concentrations of PNPP are low, notwithstanding when concentrations of PNPP are already high, increases in PNPP concentration resulted in particular or no increase in the rate of output signal of PNP. Introduction An enzyme is a protein that catalyzes a chemical reaction.

An enzyme works by increasing the rate of reaction by bringing reactants together in the proper preference and thus decreasing the activation energy. activation energies! drop because enzymes destabilize bonds in the reactant, stabilize the transition state, contrive acid-base reactions more favor able, and change the reaction mechanism through a covalent bind interaction (Freeman 2002). Enzymes also catalyze particularized reactions because its active site is able to accept one or a rattling limited number of substrate molecules that willing be able to bind to...
