Effect of enzyme concentration on rate of reaction Research question: is there a relationship between catalase concentration and the rate of reaction? Hypotheses: if the enzyme concentration is increased then the rate of reaction will increase. If the enzyme concentration is decreased then the rate of reaction will decrease. Controlled: temperature Independent: % catalyze concentration ( Dependent: rate of reaction (mm/s) Materials: Mortar and pestle Graduated cylinder Distilled

Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. In the enzyme lab‚ the effects of concentration‚ temperature and pH on the functionality of the enzyme catalase. The enzyme lab was also about measuring reactions by capturing the oxygen that was generated by the reaction. Materials and Methods: Experiment 1‚ 2‚ & 3 Experiment 1 examined the effects of concentration on catalase activity. Experiment 2 examined the effects of concentration in temperature

Presence of Alu element within PV92 on chromosome 18 in a mixed ethnical population and its connection with humans’ ancestral origins By Shiyu Song Biology 155Q LAB-A: 14:30-17:30 Dr. Jacob April 17th 2013 Abstract The Alu insertion (+) within PV92 on chromosome 16 usually reflects a person’s ancestral origin. This study aimed to find the correlation between the presences of Alu insertion (+) within PV92 on chromosome 16 within a population. We used PCR to detect the Alu insertions

I. Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration

Shalacia Gilmore Fall 2012 BIO 1107 Natural Selection Lab INTRODUCTION In the 1850s‚ two scientists by the name of Charles Darwin and Alfred Russell Wallace composed the theory of evolution by natural selection. (1) Darwin characterized several claims needed for natural selection to happen‚ including heritable variation within the population‚ and the presence of more individuals than the environment can support. They also discovered that certain environments favored certain traits. These

Purpose: To observe epithelial tissue by using a microscope to compare prepared slides. Introduction: Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialized to form the covering or lining of all internal and external body surfaces. Epithelial tissue can be divided into two groups depending on the number of layers of which it is composes. Epithelial tissue which is only one cell thick is known as

Synthesis of Butyl Benzoate Using Phase Transfer Catalysis The objective of the experiment is to synthesize the butly benzoate by nucleophilic substitution and characterize it by IR spectroscopy. The percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask
