The Identification and Production of Materials 1. Fossil fuels provide both energy and raw materials such as ethylene‚ for the production of other substances. Students Learn To: .2 Identify the industrial source of ethylene from the cracking of some of the fractions from the refining of petroleum. • Ethylene is produced either from natural gas or crude oil‚ which are mixtures of hydrocarbons. One method involves… Cracking: a process by which hydrocarbons with higher molecular

fermentation of wort‚ a liquid rich in sugars‚ nitrogenous compounds‚ sulphur compounds and trace elements extracted from malted barley. Fermentation is the process by which glucose is converted to ethanol and carbon dioxide and is expressed chemically as: C6H12O6 + 2PO43- + 2ADP → 2C2H5OH + 2CO2 + 2ATP Behind this simplified chemical reaction is a series of complex biochemical reactions. These reactions (known as the ‘Glycolytic pathway’ or ‘Embden-Myerhof-Parnas pathway’) involve a number of enzymes and the

BIOLOGY LABORATORY Biologically Important Molecules Carbohydrates‚ Proteins‚ Lipids‚ and Nucleic Acids Objectives In this lab you will learn to: 1. Perform tests to detect the presence of carbohydrates‚ lipids‚ proteins‚ and nucleic acids 2. Recognize the importance of a control in a biochemical test 3. Use biochemical tests to identify an unknown compound Introduction Organic molecules are those primarily made up of carbon‚ hydrogen and oxygen. The common organic compounds of living

(Remember that electrons are a source of Kinetic Energy.) B. With O2 present in the cell – Cellular Respiration can occur in the mitochondria. C. Without O2 present in the cell – Fermentation will occur in the cytoplasm of the cell.

Sept 27‚ 2010 Chapter 4 * With four valence electrons‚ carbon can form four covalent bonds with a variety of atoms * This tetra valence makes large‚ complex molecules possible * Fundamental groups: Alkanes and Alkenes * The electron configuration of carbon gives it covalent compatibility with many different elements * The valences of carbon and its most frequent partners (hydrogen‚ oxygen‚ and nitrogen) are the “building code” that governs the architecture of living
