Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1‚000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)

Introduction: This lab helps further our understanding of essential principles behind diffusion and osmosis. Permeability‚ concentration gradients‚ plasmolysis‚ water potential‚ and equilibrium were also concepts that were delved into in this lab. Understanding how diffusion and osmosis works is essential to understanding biology. Each time a cell has something move into or out of it‚ some sort of principle studied in this lab is occurring. Diffusion‚ osmosis‚ and passive and active transport are

Density Lab January 24‚ 2014 Benjamin I. Purpose- The purpose of this lab is to identify the unknown substances by calculating the densities of the given substances then comparing those densities to the actual densities on the table given. II. Materials- Graduated cylinders Triple beam balance Unknown substances from bag given by teacher Table of known densities Calculator Water III. Procedure- The first thing one must do to identify which substance is which is to calculate the

string to a 50 g weight hanger and drape the string over the pulley. The string length should be such that‚ when one hanger hits the floor‚ the upper part of the other hanger is near the pulley‚ without touching the pulley. (You may find that the lab assistant has already set up the apparatus as described here. If so‚ double check the setup.) 2. Place equal masses of approximately 1000 g on each weight hanger. These masses should include four 5 g masses at the top of the left hanger. Hold back

Chem 105 Guide to the Formal Laboratory Report The purpose of a formal report is to communicate effectively to another person the goal‚ procedure‚ data analysis method‚ and results of your laboratory work. The report is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical
