BIO 123 Notes January 11 *Download lecture 3 slides & do mastering biology Building Blocks of Life PPT Structure and function are relation We can infer knowledge about things we may not understand. Important to understand basic form. Form of an Atom Components: electron, proton, neutron. Protons & neutrons in center while electrons are outside. Charges: Neutrons (no charge, good for mass). Protons (+ charges). Electrons (- charge). Ions: any time protons and electrons aren’t the same. Can be positive or negative. How form and function relate Isotopes: varying numbers of neutrons Period table of elements Need to know: atomic number and atomic weight Bohr model of Na: first shell=2 e-, second shell= 8 e-, third shell= 1 e- positive ion Bohr model of Cl: first shell= 2 e-, second shell= 8 e-, third shell= 7 e- negative ion A “Bonding” experience Ionic bonding Good, strong bonding Covalent bonding Water: Oxygen needs a pair of e- to become stable. So shares two hydrogens. BIO 123 January 13, 2016 Ionic Bonding Covalent Bonding Alternative to ionic. Sharing electrons. Partial charges is when there’s more pull one way than the other. Water! Polarity gives water its characteristics. Polar Covalent Bonds allow Hydrogen Bonds Bonds ranked from strong to weak: ionic, covalent, then H. Weak bonds, but a lot of function. Carbon Basis of life forms. Forms a lot of covalent bonds. Biomolecules held together by covalent bonds, and it forms 4 of them. Makes for a really good backbone for a lot of molecules. Polar covalent bonds along with Hydrogen bonds lead to some interesting properties of water Water and pH Powerpoint Water- why important? As we age, we lose water. Can have as little as 47% water. A lot in cardiovascular system. Life can be sustained in water even under a blanket of ice. Earthworms look for oxygen by coming to the surface. Unique properties of water Vocabulary Solute: something we dissolve in a solvent Solvent: what we dissolve the solute in Solution: solutes + solvents We can dissolve anything in water except for nonpolar covalent bonds Water needs Consumption of water through history Our society consumes so much water compared to others. Although hasn’t always been that way. State of water on our planet Large portion of the world doesn’t have safe water. Our picky drinking habits have started to cause health problems Water as a universal solvent We can measure how much H+ is in the solution, and measuring gives us a pH scale H+ = acidic, OH- = basic pH Ratio- one goes up, the other goes down. pH Scale is logarithmic Scale depends on ratio. Exactly equal (H+ and OH-), neutral. Neutral= PURE water @ pH 7 6 through 0 = acid From 6 to 4 = 100 fold change Maintaining pH is part of homeostasis pH, water and environmental issues Highest point in Eastern app
