------------------------------------------------- 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 since the pressure of

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

which he called cells’ this in itself unbeknownst to him‚ was the discovery of the fundamental unit of all living things. In 1838 a botanist called Schleiden derived the theory The basic unit of structure and function of all living organisms is the cell.’ Over 150 years later this can be regarded as one of the most familiar and important facts within the biological fields.

going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules of one substrate. The site of the reaction occurs in an area on the surface of the protein called the active

Anna Nordseth Block 3 Biological Warfare During WWII the United States took part in a new method of fighting the enemy: biological warfare. This way of fighting proved to be effective in both monetary cost and the toll taken in human lives. The United States and Great Britain developed the technology to make bombs out of the deadly anthrax virus. These were to be shot at enemy territory which would cause a widespread outbreak of anthrax virus. It was thought that the leftover anthrax spores

Enzyme lab report. Introduction. An enzyme is a protein molecule that speeds up the rates of chemical reactions by many folds. They recognize‚ bind‚ and change specific reactants. They do not change thus can catalyze the same reaction again and again. Activation energy also known as an energy barrier is the amount of energy needed in order to begin a chemical reaction. Catecholase catalyzes the reaction rate of catechol oxidation. Catechol is found beneath the skin of many plants such

• Chapter 7 o Online questions • The fluid mosaic model is now generally accepted for the description of all biological membranes • Transmembrane segments of membrane proteins anchor membrane proteins in the lipid bilayer. • A ganglioside is not a phospholipid. • Thin-layer chromatography separates lipids based on hydrophobicity. • Unsaturated fatty acids have double bonds and increased membrane fluidity. • Cholesterol increases fluidity at low temperatures and decreases fluidity at high temperatures

During the process of helicase breaking the hydrogen bonds between the two strands of the double helix structure of DNA where it forms a replication fork‚ Gyrase releases the tension in the strands by relieving twist at swivel points. The enzyme RNA polymerase (or primase) makes a piece of a RNA which is called a primer) against to the exposed DNA. Then DNA polymerase causes free nucleotides (from digested food) to bond to the exposed DNA bases adjacent to the primer and so form a new side
