BIOLOGY LAB REPORT (UNIT 7: ENZYMES) GENERAL Enzymes are protein that acts as catalyst‚ lowering the activation energy need for reactions to progress in cells. The reaction can still occur without the presence of the enzyme‚ but at a much slower rate. The activation energy is the minimum amount of energy need for a chemical reaction to occur‚ yielding from a given set of reactants. In enzymatic reactions‚ we have substrates which are reactants of reaction bound to an enzyme. While an active site is

Free sample essay on My School for kids. I study in Cambridge School which is one of the best schools of Mumbai. It has a stone building. It has all the facilities a good school should have — well-furnished classrooms‚ laboratories‚ library and playgrounds. As we enter the school‚ there is a playground to our left and a small garden to our right. When we enter the building‚ the Principal’s room and the office room are to the left and the staff room to the right side. These are well-furnished

------------------------------------------------- Enzyme Pre-Lab Harry Kang 9/26/12 1) The purpose of this lab was to determine the rate of enzyme activity under variety of different conditions‚ such as‚ different amount of drops of enzymes and different temperature of water. The class measured the pressure in the test tube during the reaction of the substance with‚ 1.5 ml of H2O2‚ 1.5ml of H2O and different amounts of enzyme drops‚ to determine how much oxygen gas is produced during the reaction

Lab: Catalase (Enzymes) Abstract In this laboratory exercise‚ studies of enzyme catalase‚ which accelerates the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. The laboratory was also conducted in association with a second laboratory that measured the effects of an inhibitor on the enzymes. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration

1. The total amount of fiber that I consumed for the day was 39 grams. 2. The total amount of fiber recommended for my age group according to (Williams & Wilkins‚ 2013) is thirty-eight grams. I happened to be one gram above the fiber recommended daily intake for the age group of 19-50 years of age. 3. To increase an individual’s fiber intake I highly recommend simply replacing refined with whole grain products. One tip on getting more fiber into your daily diet is to try getting

The exploratory phase (Exp No. 1) has highlighted bio-reduction ferrihydrite by Shewanella oneidensis MR-1‚ which occurs only in the presence of formate (carbon source and electron). The Exp # 2 showed that the presence of the bacterium and iron oxide in the reaction medium (E-Sh-Ox) promotes the disappearance of endosulfan but inhibits its hydrolysis (and thus its transformation into ES-diol ) susceptiblement by more effective adsorption phenomenon. It is observed in this case 89.45% α + β O disappeared

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

Potato Enzyme Lab INTRODUCTION An enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism. A good rule of thumb is to remember that enzyme names end in “-ase”. This will help in identifying enzymes in further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The
