Enzymes are biological catalysts that operate at the temperatures‚ pressures‚ and moderate pH values found in living organisms. They help in a faster chemical reaction in our human body. Besides this‚ enzymes also play a huge role in various industries. The following paragraphs will talk about how various enzymes are used in various industries : The Dairy Industry and Medical Industry. In the dairy industry‚ the enzyme Protease is used widely. While making cheese‚ protease helps coagulate milk

Effects of Different Concentration of Catalyse on Hydrogen Peroxide Aim: In this investigation I will try to find how long it takes for the filter paper disc to rise up whilst varying the amounts of concentration of catalyse. Prediction: I predict that the lower the concentration of catalyse the longer it will take for the filter paper disc to rise to the surface of the tube. Equipment: 1. Hydrogen peroxide in a container 2. Flat bottom tube 3. Tweezers 4. Filter paper

Enzymes in Living Tissues Purpose: The purpose of the lab was to analyze the enzymes in living tissues‚ represented by the pieces of liver. Also‚ hydrogen peroxide was used to demonstrate these effects. Storyboard: Materials: 2 50 mL beakers 10 mL graduated cylinder 3% hydrogen peroxide solution Hot water bath Lemon juice or HCl Fresh liver Forceps Procedure: Measure 10 mL of hydrogen peroxide and record its temperature. Pick the liver up with the forceps and

Direction and concentration gradients Bradley Benton ABSTRACT In this experiment‚ we will investigate the effect of solute concentration on osmosis. A semi‐permeable membrane (dialysis tubing) and sucrose will create an osmotic environment similar to that of a cell. Using different concentrations of sucrose (which is unable to cross the membrane) will allow us to examine the net movement of water across the membrane. INTRODUCTION A major determinant of diffusion in a biological system is membrane

The experimental results were different from the hypothesis because while the enzyme appeared to not work as well‚ I expected a more significant change. Most of the time‚ there was only a millimeter of difference of the foam between the two samples while I expected a greater difference such as 10 millimeters. Enzymes speed up chemical reactions and at the active site‚ a substrate can be broken down or two substrates can form a larger molecule. Hydrogen peroxide is broken down by peroxidase into water

Concentration Camps in the Holocaust World War II brought many atrocities‚ 6 million to be precise (Wachsmann 2017). With so many camps not even discovered yet‚ as they are still doing an investigation into all of the locations of the camps‚ but we may not even know how many deaths and the torture of the prisoners by the Fuhrer and the Nazi’s. The Germans had many uses for the concentration camps. A concentration camp is a detention site outside the normal prison system created for military purposes

supernatant liquid and denser slurry having a higher concentration of solids. This is usually accomplished by allowing the particles to settle through the force of gravity‚ mechanically using centrifugal force‚ or electrostatically using an electric current. Continuous sedimentation tanks are usually used in wastewater treatment facilities to separate suspended particles from wastewater. This experiment aims to determine the effect of initial concentration and initial height of the slurry on its settling

1997X A radiochemical enzyme assay for studying cyclooxygenase (COX)-catalyzed prostaglandin biosynthesis in vitro was optimized with respect to both COX-1 and COX-2 activity. The assay can be used to assess the relative selectivity of plant-derived inhibitors on COX-1 and COX-2. Assay conditions were optimized for both enzymes with respect to concentration of cofactors (l-epinephrine‚ reduced glutathione‚ and hematin)‚ activation time (enzyme and cofactors)‚ reaction time‚ and pH. Moreover‚ the

Effects of pH on the Function of Enzymes Rena Mototani Glen Rock High School Advanced Biology 2014-2015 Effects of pH on the Function of Catalase Rena Mototani Problem: How does the pH of a cell affect the function of the enzyme catalase? Introduction In this lab‚ we experimented the effects of pH on the function of the enzyme catalase. Catalase is an enzyme that brings about the reaction by which hydrogen peroxide is decomposed to water and oxygen (Encyclopedia Britannica). The
