    • SLIDE LAYOUT
      • Create your own slides
        • -- canned lectures generally are not interesting.
    • CANNED TEXTBOOK SLIDES
    • Electron Transport System
      • As electrons pass down the electron transport system, energy is captured and ATP is produced.
        • Oxidative phosphorylation refers to the production of ATP as a result of energy released by the electron transport system.

    • RANGO SLIDES
    • OVERVIEW OF CELLULAR RESPIRATION
    • WHAT IS THE ELECTRON TRANSPORT SYSTEM?
      • series of membrane-bound carriers that transfer electrons from one carrier to another
      • each transfer results in a release of energy
      • high energy electrons enter, low energy electrons exit
      • each carrier is reduced and then oxidized in turn
    • WHAT IS A CYTOCHROME COMPLEX?
      • bunch of cytochrome proteins in membrane
      • cytochrome protein contains iron atom (similar to hemoglobin)
      • iron atom helps transfer electrons instead of oxygen
    • ELECTRON TRANSPORT SYSTEM
      • located in cristae of mitochondria
      • high-energy electrons enter, low-energy electrons leave
      • oxygen is final electron acceptor
      • as electrons pass down ETS, energy is captured and ATP is produced
      • NADH  3 ATP
      • FADH 2  2 ATP
    • Fig. 8.8 HOW IS ATP MADE IN ELECTRON TRANSPORT SYSTEM? OXIDATIVE PHOSPHORYLATION: Production of ATP from energy released by ETS. H + pumped into intermembrane space. H + flow down concentration gradient into matrix. ATP made by ATP synthase  chemiosmosis.
    • Fig. 8.9 ENERGY YIELD FROM GLUCOSE BREAKDOWN 39% of available energy transferred from glucose to ATP. Rest is lost as heat. Difference due to shuttle mechanism (NAD + or FAD).
    • SLIDE LAYOUT
      • Simplify the background
        • -- avoid busy design templates.
        • -- use a dark background.
    • SLIDE LAYOUT
      • Minimize text
        • -- use bullet sentences.
        • -- use large font (28 point or greater).
        • -- use contrasting color for words.
    • SLIDE LAYOUT A lot of times people include way too many words on the slide and proceed to read the entire slide to the students. Additionally, the font is often way too small and the color of the words not different enough from the background to be easily read. If I were to show a lot of slides like this one, I guarantee that students would doze off and no longer pay attention. Using short sentences, beefed up font, and a contrasting color for the words increases the focus of students. In fact, a black background with white letters seems to help students focus even better than most color combinations.
    • SLIDE LAYOUT
      • Show interesting images
        • -- BIG, BRIGHT AND BEAUTIFUL.
        • -- get images from:
        • * textbook
        • * internet
        • * digital cameras + microscopes
    • PHOTOSYNTHESIS LAND PLANTS MULTICELLULAR ALGAE UNICELLULAR PROTISTS CYANOBACTERIA OTHER PHOTOSYNTHETIC PROKARYOTES
    • LIGHT REACTIONS
    • EVOLUTIONARY THOUGHT: late-eighteenth century
      • Jean-Baptiste de Lamarck (1744-1829)
        • Evolution occurs.
        • Diversity of species due to adaptation to environment.
        • Fossil record  more complex organisms are descended from less complex organisms.
        • Inheritance of acquired characteristics.
    • VIRUSES INFECTING A BACTERIAL CELL
    • 1950s FRANKLIN’S X-RAY DIFFRACTION PHOTOS Photo made by Rosalind Franklin, seen by Watson and Crick, led to the discovery that DNA was a double helix composed of two strands.
    • Smallest unit of living matter = CELL
    • DIFFERENT KINDS OF ENERGY KINETIC ENERGY = energy of motion POTENTIAL ENERGY = stored energy KINETIC ENERGY POTENTIAL ENERGY
    • SLIDE LAYOUT
      • Avoid gimmicks
        • -- tone down custom animations.
        • -- don’t use slide transitions.
        • -- avoid noises.
        • -- KISS
