    Title: Enzyme Activity Lab Purpose: To measure the rate of enzyme activity from a tissue abstract and experiment with different factors‚ such as the enzyme solution and the substrate with different hydrogen peroxide percentages and temperature‚ that affect enzyme activity. Hypothesis: 1) If the disk is placed into each beaker with 100 units/ml of enzyme solution‚ then the time for the disk to float will be 30 seconds. 2) If the temperature of the solution is at 5 degrees Celsius‚

    Hydrogen has a high specific energy‚ high flame speed‚ wide range of flammability‚ and clean burning characteristics which suggest a possibility of high performance in internal combustion engines (ICE). These attributes have been realized for more than half a century since the onset of hydrogen engine development. In the early 1990s‚ FSEC conducted research on using hydrogen in an ICE. This work resulted in the development of a mixed fuel called HYTEST. Today‚ automobile manufacturers and DOE continue

    In the humus lab were were trying to find out if hydrogen peroxide would cause a reaction and show us the amount of humus in the soil by putting gas into a graduated cylinder with water to make the water level lower therefore showing us how much humus the material being tested contained. It showed that the sand was lacking humus but the mushroom compost was the most rich in humus. My hypothesis was correct because I predicted that the mushroom compost would produce the greatest amount of humus out

    Ashley Esparza Stallings Period 2 January 26‚ 2013 Enzyme Catalysis Lab Report Background: Enzymes are catalyst‚ which affect the rate of a chemical reaction. One consequence includes the cell to carry out complex chemical activities at relatively low temperatures. In these reactions the substrate binds reversibly to the active site. The cause of this is a decrease in the energy needed to activate the reaction of the substrate molecule to from products. Every enzyme is particular for a

    LAB 10: NAME: DaeNia La Rodé DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without

    LSM1102 Lab Report Introduction Transformation is a process which involves plasmid DNA being bound to the cell surface and the subsequent uptake of DNA by the cell (Panja et al.‚ 2008). For artificial transformation of E. coli cells with plasmids‚ plasmid DNA has to be extracted from bacterial cells using the High-Speed Plasmid Mini Kit‚ which is then mixed with competent E. coli cells followed by heat shock and the streaking of transformed cells on two different types of agar plate (LB and LB+ampicillin)

    we performed two different experiments that investigated the effect of varying substrate concentration‚ and the effect of temperature on the rate of Enzyme-Catalase reaction. In experiment one (i.e. the effect of varying substrate concentration on the rate of enzyme-catalase reaction) we tested the hypothesis HA as substrate concentration increases‚ so will reaction rate until all active sites are bound. In experiment two (i.e. The effect of temperature on the rate of enzyme-catalase reaction) we tested
