Using different chemical seed soaks to improve the rate of germination A 2013 Year 9 Science Project by Josh Martin Class Level 1 with Mr Box Abstract: The purpose of this investigation was to determine which out of five readily available chemicals was the most effective at scarifying seeds to improve the rate of germination‚ and what concentration of the most effective chemical was the most efficacious. Ten seeds for each of the five chemicals hydrogen peroxide‚ glucose

Harris October 18‚ 2011 Biology Lab report Proteins are very important throughout the body. They have a lot of functions in cells. Antibodies are proteins that help cells rebuild the cells when they are destroyed. Transport proteins move substances from one place to another. Regulatory proteins control cellular metabolism in a way that cells throughout the body can have the right amount of glucose in the blood. A common protein is an enzyme; in cells they speed up chemical reactions. For an example

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

Enthalpy of Reaction and Hess’s Law December 5‚ 2011 Kylie Case‚ Emma McKee‚ Rebecca Smith Purpose: In this lab‚ the purpose was to verify Hess’s Law. Theory: Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The first being enthalpy of reaction‚ ΔHrxn‚ which is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant pressure in the reaction

The Determination of the Concentration of Hard Water Ions by the Titration of EDTA By Hannah Denby Lab partners: Heidi Kiziah‚ Leonie Hamel University of Central Florida‚ CHM 2046L December 3rd‚ 2015 Abstract. The “hardness” of water is a common dilemma attributed by high concentrations of metals such as calcium and magnesium. This is a result of the properties of water; because it is a good solvent‚ impurities are easily dissolved. As water moves through soil and rock‚ it dissolves minute amounts

Determining the Catalytic Properties of the Enzyme Peroxidase Extracted from a Turnip Under the Conditions of Temperature‚ pH‚ Boiling and Competitive Inhibitors By Robin Caserta BIO 101 September 30‚ 2013 ABSTRACT The enzyme‚ peroxidase‚ extracted from a turnip was tested for its efficiency in binding to its substrate and its stability under several conditions. To do this‚ we tested effects on peroxidase activity‚ first‚ with different amounts of the enzyme‚ next at temperatures of
