Biology Re V iew Chapter 2 By: Vaibhav Mokashi Topic Details Matter in Ecosystems Organic Matter Generally found as the main components in living matter except water. They are usually carbon compounds Types of Organic Compounds Proteins Made from amino acids Structure of a typical amino acid Sugars Monosaccharide glucose (C 6 H 12 O 6 ) Disaccharides Sucrose (C 12 H 22 O 11 ) Polysaccharides Starch, cellulose, glycogen - (C 6 H 12 O 6 ) n *Every time two monosaccharides join an H 2 O molecule is created Fats Formed from molecules called fatty acids Inorganic Molecules These are found in living organisms. In living organisms matter is constantly cycling where important elements like C and O and H go from organs on to the other. Carbon Cycle Photosynthesis 6H 2 O + 6CO 2 + light C 6 H 12 O 6 + 6O 2 Cellular Respiration C 6 H 12 O 6 + 6O 2 6H 2 O + 6CO 2 Nitrogen Cycle Air has approximately 80% Nitrogen (N 2 ) and it is very stable and unreactive. Nitrogen however is a component of protein which all living things are made up of. In order to move or cycle nitrogen from the air into proteins it has to change into a more usable form as Nitrates (NO 3 ) -1
