Vaishnavi Kothapalli Mrs. Manning Honors Biology 30 November 2012 TITLE: The Reaction Rate of Catalase in Various Concentrations of Hydrogen Peroxide QUESTION: How long does the catalase take to float to the top of a cup filled with different amounts of hydrogen peroxide concentration? PREDICTION: A prediction that can be made for this experiment is that the higher the concentration‚ the faster time it takes the catalase to react with the solution. As the concentration increases from

TOPIC: Food Tests – Semi Quantitative Test AIM: To determine the concentration of glucose present in an unknown sample‚ using a semi quantitative glucose test APPARATUS AND MATERIALS: 4% stock solution of glucose‚ water‚ 6 test tubes‚ ruler‚ water bath‚ solution of unknown concentration (Sample A)‚ Benedict’s reagent METHOD: 1. Solutions of different concentration were made from the stock solution and placed in test tubes.

would equal to the total number of teeth present in the mammal. The dental formulas for these three species: coyote (Canis latrans)‚ deer (Odocoileus virginanus)‚ and human (Homo sapien) are all different. The coyote had the dental formula of 3-1-4-2/3-1-4-2 (x2)‚ which produced the total of 40 teeth. The deer had the dental formula of 0-0-3-3/3-1-3-3 (x2)‚ which equaled to 32 teeth. The human species had a smaller number of teeth with the dental formula being 2-1-2-2/2-1-2-2 (x2)‚ which produced a

Lab #5-Enzymes NAME DATE LAB PERIOD Introduction Enzymes are proteins‚ though highly complex and diverse‚ they serve one basic function; to work as an organic catalyst. A catalyst‚ as defined by Merriam-Webster dictionary‚ is a substance that enables a chemical reaction to proceed at a usually faster rate ("Catalyst-Definition and more."). They function by reducing the activation energy‚ or energy required to start a reaction. The way enzymatic reaction works cannot be altered‚ but the

Effect of Temperature on Enzymes ~Abstract~ In this experiment the effect of different types of temperatures on enzyme activity was examined. The temperature baths that were used to test the difference in enzyme activity on fresh liver were; 4 °C‚ room temperature which was 22°C‚ body temperature which is 37°C‚ and 77°C. The total time of each trial was 2 and a half minute‚ 1 minute for the H2O2 to acclimatize to the temperature‚ 1 and a half minutes for the reaction to occur. Catalase causes Hydrogen

Biomolecules - Biology Unit 3 What is a Biomolecule? Organic molecule made by living organisms Organic Molecules: contain carbon considered the “chemicals of life” Inorganic Molecules: Do not contain carbon Consist mostly of: carbon (c)‚ hydrogen (h)‚ oxygen (o) Monomers vs. Polymers Monomers: single-molecule that may react with similar molecules to form a chain Polymers: a chain of many monomers that are chemically bonded together

Lab Ex#8: "Enzymes: Catalysts of Life" INTRODUCTION Enzymes are protein organelles where chemical reactions take place to generate energy within our cells. Without the energy produced from the cell enzyme activity‚ we would not possess the catalyst activity necessary for energy to produce movement. Each enzyme performs a specific function within our bodies. Those functions performed can be significantly altered with the introduction of variables outside their environment. Variables‚ such as temperature

The Effect of Temperature on Enzyme Activity and Oxygen Production Throughout this report you will gain information as to how temperature effects the amount of oxygen produced in an enzyme- catalase experiment. In the experiment we used liver extract as a catalase and created a chemical reaction within a reaction chamber between the catalase and hydrogen peroxide as well as three different controlled temperatures. In the procedure below there will be a step by step process as to how

Enzyme Lab Using Jello INTRODUCTION: Enzymes are known as protein catalysts. The name protein catalyst suggests that most enzymes are made of proteins. A catalyst is a substance that speeds up chemical reactions without being consumed in the process. (Giuseppe‚ M 2002‚ p.69). After a reaction has been catalyzed‚ the catalyst can be used again to catalyze the same reaction. Enzymes reduce the activation energy (minimal energy) it takes for a reaction to take place. Enzymes can either catabolize
