Jenniffer desimone, monday lab, lab Performed: 11/6/00, lab Submitted: 11/13/00. Introduction: Within each of our body cells are thousands of enzymes.

Enzyme lab

Objective: to demonstrate proposal the activity of enzymes under different conditions. Materials: 1) Hydrogen Peroxide. 2) Scoops up all the ground material and place it into another test tube containing about a half-inch of fresh H2O2. 4) Repeat the same procedure, using small chunks of organic materials that are available at your resume or the teacher? Results: Q: What happens when raw liver is placed in H2O2? A: A lot of bubbling occurs. Catalase Activity in Various Substances. Substance, amount of Bubbling Rating by number. Frozen liver Many 2, boiled liver None 5, vinegar-soaked liver A little. Fresh liver A lot 1, conclusions: Q: How do we know that Catalase was present in our living materials?

The solution should progress in the colors of blue (with no glucose present green, yellow, orange, red, and pdf then brick red when there is a large amount of glucose present. (Google benedict's test to see the way this looks.) Design an experiment where you would determine how quicly lactaid works to break down milk sugar at different temperatures. Be specific in your description, use drawings if necessary. Enzyme Activity Essay, research Paper, enzyme Activity in the liver, lab 6. Lab Performed: 11/6/00, lab Submitted: 11/13/00, introduction: Within each of our body cells are thousands of enzymes. These enzymes are proteins, or chains of amino acids that are responsible for chemical reactions. Enzymes are also called organic catalysts. A catalyst is a substance that speeds a chemical reaction without getting changed much itself. Ll be using in this experiment is Hydrogen Peroxide or H2O2.

Liver Blood Tests, abnormal Values (High, low) Explained

Propose a way to refine your experiment to find the night exact, or optimal pH and temperature of catalase. The following graph shows reaction rates of various enzymes in the body. . Pepsin is found in the stomach, amylase in the saliva, and phosphatase in the liver. Synthesis: How does pH affect the activity of enzymes? Claim: evidence: reasoning: Part literature e - design an Experiment Lactaid is a product designed to help people who cannot digest milk sugar (lactose) because they are missing the enzyme lactase. Many people are lactose-intolerant, a condition that is mainly genetic. Lactase breaks down lactose into two subunits: glucose and galactose. To test for the presence of monosaccharides and reducing disaccharide sugars in food, the food sample is dissolved in water, and a small amount of Benedict's reagent is added.

Put equal quantities of liver into 2 clean test tubes and 1 ml H2O2 into 2 other test tubes. Put one test tube of liver and one of H2O2 into an ice bath. Place the other set in a warm water bath (not boiling). After 3 minutes, pour each tube of H2O2 into the corresponding tube of liver and observe the reaction What is the reaction rate for the cold liver/peroxide? _ What is the reaction rate for the warm liver/peroxide? _ Synthesis - how does temperature affect the catalase enzyme? Claim: evidence: reasoning: part d - what is the Effect of pH on Catalase Activity. Add 2 ml hydrogen peroxide to 4 clean test tubes, then add: Tube 1 add 3 drops of acetic acid (vinegar)  pH _ Tube 2 add 3 drops of sodium bicarbonate (base) pH _ Tube 3 add 3 drops of water (neutral) pH _ Tube. How does  pH affect the reaction rate of catalase?

What Is, drug Induced liver Disease?

You will now test for essay the presence of catalase in tissues other than liver. Place 2 ml of hydrogen peroxide in each of 3 clean test tubes and then add each of the three test substances to the tubes. As you add each test substance, record the reaction rate (0-5) for each tube. Substance, apple, potato, yeast. Rate of reaction (0-5 synthesis - do all living tissues contain catalase? Claim: evidence: reasoning: part c - what is the Effect of Temperature on Catalase Activity?

Put a piece of liver into the bottom of a clean test tube essays and cover it with a small amount of water. Place this test tube in a boiling water bath for 5 minutes. Remove the test tube from the hot water bath, allow it to air cool, then pour out the water. Add 2 ml of hydrogen peroxide. Caution: Use a test-tube holder for hot test tubes. What is the reaction rate for the boiled liver and peroxide?

Assume that the reaction in step 2 proceeded at a rate of "4". Recall that a reaction that absorbs heat is endothermic; a reaction that gives off heat is exothermic. Feel the temperature of the test tube with your hand. Has it gotten warmer or colder? Is the reaction endothermic or exothermic? Pour off the liquid into a second test tube.

Assuming the reaction is complete, what is this liquid composed of? What do you think would happen if you added more liver to this liquid? Test this and record the reaction rate. . Reaction Rate _  (1 5). . Add another 2ml of hydrogen peroxide to the liver remaining in the first test tube.  What is the reaction rate? Synthesis, answer the question:  Is catalase reusable? Claim : evidence, reasoning. Part b - what Tissues Contain Catalase?

Detox flush, how to rebuild

Warm water bath, boiling water bath, part a - observe normal Catalase reaction. Place about 2 ml of the 3 hydrogen peroxide solution into a clean test tube. Using forceps and scissors cut a small piece of liver and add it to the test tube. Push it into the hydrogen peroxide with a stirring rod. What gas is being released? (consider biography the equation above). Throughout this investigation you will estimate the rate of the reaction (how rapidly the solution bubbles) on a scale of 0-5 (0no reaction, 1slow.

study the catalase found in liver cells. You will be using chicken or beef liver. It might seem strange to use dead cells to study the function of enzymes. This is possible because when a cell dies, the enzymes remain intact and active for several weeks, as long as the tissue is kept refrigerated. Materials: 6 Test tubes, test tube holders 3 Hydrogen peroxide, straight-edged razor blade. Scissors and Forceps, measuring Pipettes, stirring rod, fresh liver, Apple, and Potato, yeast. Vinegar / baking Soda, hcl and naoh pH paper (optional ice bath.

Enzymes are proteins that speed up the rate of reactions that would otherwise happen more slowly. The enzyme is not altered by the reaction. You have hundreds of different enzymes in each of your cells. Each of these enzymes is responsible for one particular reaction revelation that occurs in the cell. In this lab, you will study an enzyme that is found in the cells of many living tissues. The name of the enzyme is catalase; it speeds up a reaction which breaks down hydrogen peroxide, a toxic chemical, into 2 harmless substances-water and oxygen. Light can also break down H2O2 which is why the chemical is sold in dark containers. The reaction is: 2H2O2 2H2o.

J k, l m, n o, p q, r s, t reviews u,. Date objectives, measure the effects of changes in temperature, ph, and enzyme concentration on reaction rates of an enzyme. Explain how environmental factors affect the rate of enzyme-catalyzed reactions. Introduction: What would happen to your cells if they made a poisonous chemical? You might think that they would die. In fact, your cells are always making poisonous chemicals. They do not die because your cells use enzymes to break down these poisonous chemicals into harmless substances.
