    on Enzyme Activity Rate Abstract The reaction rate of an enzyme can be affected by many factors‚ and the purpose of this experiment was to find out how an increasing substrate concentration influences the rate of an enzyme activity; we obtained data from recording the absorbance of the samples which contain the same amount of potato juice (enzyme oxidase) and different amount of catechol (substrate) while holding pH and temperature constant. Our findings illustrate that the rate of enzyme activity

    on the rate of enzyme activity of Catalase Aim To investigate the effect of substrate concentration (manipulated by increasing concentration of hydrogen peroxide) on the rate of enzyme activity of catalase‚ produced by liver cells‚ on the decomposition of hydrogen peroxide. Introduction Enzymes are biological catalysts that increase the rates of reactions. In an enzyme-catalyzed reaction‚ the substrate binds to the active site and forms enzyme-substrate complex with the enzyme through the lock

    Enzymes are protein‚ they are used to catalyse metabolisms in all organisms. They break down complex molecules and build up complex molecules from simple molecules‚ these two processes are catabolic reaction and anabolic reaction respectively. Enzymes are needed in these two processes to catalyse releasing and taking up ATP molecules. Different sequence of amino acid produces different structure of protein‚ which determines the property of protein‚ thus each kind of enzymes has its unique active

    Rate of Enzyme Activity Justin Hunter G. Kim September 16‚ 2011 September 26‚ 2011 Abstract Catalase is a common enzyme found in nearly all living organisms that is frequently used by cells to rapidly catalyze the decomposition of hydrogen peroxide into less reactive oxygen and water molecules. Catalase is a protein that is most commonly found in the liver. The purpose of this experiment was to determine the effect that changes in temperature and pH have on the function of the enzyme catalase
