Lab #1: Cell Membrane Prepared for Gary V. Lawrence Biology 0983 By Zane Jeffels Partners: Lily Juno‚ Huynh‚ and Lin Yan Sun Preformed: October 11th‚ 2010 Due: October 25th‚ 2010 King Edward Campus- Rm. 3275 Vancouver Community College Abstract The purpose of this lab was to determine if hemolysis would occur‚ and how long it would take to occur to red blood cells when blood suspension is introduced to solutions prepared at different temperatures

LAB REPORT 1 - LAB 7 CELL MEMBRANE FUNCTION Marisela Camacho Legarreta June 30‚ 2013 ACTIVITY 1 INTRODUCTION Be aware that all molecules have kinetic energy‚ which means that is an active energy that is always in motion. Molecules move in all different ways and this create an evenly distributed movement which is best known as diffusion. Diffusion is the movement of molecules from a region of their higher concentration to a lower concentration. METHODS Check the reaction of different

stereochemistry General Concepts The most common of the variety of methods available for preparing alkyl halides is the replacement of the hydroxyl group of an alcohol. This type of reaction is representative of an important class of reactions in organic chemistry called nucleophilic aliphatic substitution reactions. There are numerous ways of doing this transformation‚ and we will discuss these in lecture. In this experiment you will convert an alcohol to an alkyl halide by reaction with a hydrohalic

Experiment 2 The Cell Membrane Abstract The boundary between any cell and its environment is the plasma membrane‚ composed of a matrix of phospholipid molecules along with a number of different kinds of proteins. Membranes have different properties and a variety of functions‚ in large part determined by the specific proteins within the membrane. This experiment is designed to determine the stress that various factors‚ such as osmotic balance‚ detergents and pH‚ have on biological membranes. There are three

C H A P T E R 5 Basic Concepts from Organic Chemistry 5.1 | INTRODUCTION The fundamental information that environmental engineers and scientists need concerning organic chemistry differs considerably from that which the organic chemist requires. This difference is due to the fact that chemists are concerned principally with the synthesis of compounds‚ whereas environmental engineers and scientists are concerned‚ in the main‚ with how the organic compounds in liquid‚ solid‚ and gaseous wastes

Write a 4-6 page paper on a subject approved by the instructor (either picked from the list below or picked by yourself). Emphasis in the paper should be on the organic chemistry associated with the subject (how it is synthesized‚ uses‚ etc.). No two students can research the same subject. Maximum value of the paper will likely in the 20-40 point range‚ depending

The two primary sources of organic compounds are oil and coal. Other sources of organic compounds are plants‚ animals‚ and microorganisms. Hydrocarbons are organic compounds that contain only carbon and hydrogen. There are various classifications of hydrocarbons.

Colton Kuhlers Chemistry Paper Organic vs. Non-Organic What should I eat‚ organic or non-organic? This has been is hot topic a lot now that the United States is trying to go healthy. For years people have been researching which is healthier‚ more economical‚ and the most available than the other. It is hard to know what to buy when one researcher says organics better and another researcher says non-organics better. Let me take this topic into more depth to explain myself. First‚ let’s me describe
