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

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

effect of pH on enzyme activity Rationale Amylase is an enzyme involved in the digestion system which catalyses the breakdown of starch into sugars. It is not only present in human saliva but also in the pancreas‚ where it hydrolyses dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. pH has an effect on the activity of all enzymes‚ including amylase. As the pH level increases‚ the enzyme activity increases‚ up until

Enzyme Activity Lab Hypothesis: 1] Are enzymes reusable? Yes‚ enzymes are reusable. 2] Which of the following do you think contain catalase? [Manganese dioxide‚ chicken meat‚ apple‚ carrot‚ potato‚ or chicken liver] I think that the manganese dioxide‚ apple‚ and carrot contain the catalase. 3] Would grinding the materials affect enzyme activity? I think that grinding the materials will increase enzyme activity. 4] Would temperature affect enzyme activity? I think that
