BOTANY 130 Final: COMPLETE STUDY GUIDE FOR EXAM #1
Document Summary
Can not be broken down any smaller. 6 elements make up 99% of everything! (c,h,n,o,p,s: elements of life = (shnops) The atom is the smallest unit of matter: proton = (+) charge, electron = (-) charge, neutron = (o) charge. Nucleic acids - made up of monomers. Lipids: not categorized as a macro-molecule. Molecule = 2 or more atoms held together by a covalent bond. Monosaccharide (e. g. glucose, n=6: cells use as fuel. Disaccharide (e. g. sucrose = glucose + fructose: transport sugars. Polysaccharide (e. g. starch and cellulose: starch = store energy, cellulose = structural purposes. * dehydration synthesis = monomer + monomer = polymer: get rid of water to form bond. * hydrolysis = breaking apart a polymer using water to make monomers. Polysaccharide: amylose = linear chain of repeated alpha-glucose monomers. E. g. potatoes, corn : cellulose = structural polysaccharide. * know the structural difference between starch & cellulose. Cellulose is flip-flopped: different structures = different functions!
