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

Introduction- This lab experiment serves as a model for community succession using bacterial colonies as the model. A bacterial colony grows from a single bacterium and is composed of millions of cells. Each colony has distinctive colony morphology: size‚ shape‚ color‚ consistency‚ and color. Community succession is a phenomenon observed in the organizational hierarchy of all living organisms. Community succession is not limited to bacterial colonies‚ but spans the entire community of life

The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation‚ the process in which a cell takes up and expresses a new piece of genetic information‚ the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their

Josh P. AP Biology 12-10-13 Lab Writeup The Effect of Transformation of pGLO in Bacteria Background/Objectives/Hypothesis: Genetic transformation is a process that primarily is inserting new DNA into an organism to change that organism’s trait. This process has many useful benefits when used correctly in different organisms. In this lab‚ bacteria was transformed by inserting DNA for Green Fluorescent Proteins. The DNA for these proteins were taken from bioluminescent jellyfish Aequorea

There is strong evidence to prove that the mitochondria once existed as a free-living bacteria‚ and were engulfed by the primitive ancestor of eukaryotic cells in a arrangement called endosymbiosis. Mitochondria have evolved over thousands of years‚ but still share characteristic with bacteria such as: their genome is a circular molecule ‚ have little non-coding DNA‚ and have their genes tightly packed with few intergenic regions between genes. Furthermore‚ mitochondria are organelles that contain

EXPERIMENT I Photoreduction of Benzophenone Introduction The study of chemical reactions‚ isomerizations and physical behavior that may occur under the influence of visible and/or ultraviolet light is called Photochemistry. The fundamental principles for understanding photochemical transformations are that light must be absorbed by a compound in order for a photochemical reaction to take place‚ and that for each photon of light absorbed by a chemical system only one molecule is activated for
