  1. Give the products of glycolysis.
    • 2 ATP (SLP)
    • 2 NADH
    • 2 pyruvuc acid 
    • *Doesn't require O2
  2. Give the important intermediates found in glycolysis.
    • Dihydroxyacetone phosphate (DHAP)
    • Glyceraldehyde-3-phosphate (GP)
  3. Know the amounts of ATP, NADH, and FADH2 made during each stage, and the entire process, of aerobic respiration.
    • Glycolysis (2 ATP, 2 NADH, 2 pyruvic acid)
    • Preparatory Step (2 NADH, 2 acetyl CoA)
    • Krebs Cycle (2 ATP, 6 NADH, 2 FADH2)
    • Chemiosmosis (34 ATP, H2O, NAD+, FAD+
  4. Know which stages and processes of aerobic respiration require oxygen.
    • Glycolysis = doesn't require oxygen
    • Preparatory step = doesn't require oxygen
    • Krebs cycle = doesn't require oxygen
    • Chemiosmosis = NEEDS OXYGEN
  5. Describe the preparatory step (transition reaction); give the reactants and products.
    • Purpose: 2 pyruvic acid (from Glycolysis) can't enter the Krebs Cycle directly
    • 2 pyruvic acids are oxidized to 2 acetyl CoA 
    • 2 NADare reduced to 2 NADH
  6. Explain the Krebs cycle; give the products and know which products are the most important to
    microbes for energy production.
    • Oxidation of acetyl CoA (from Prep Step) to CO2
    • Products = 2 ATP, 6 NADH, 2 FADH2
    • Products most important to microbes for energy production= 6 NADH and 2 FADH2
  7. Explain electron transport systems and know where they are located in prokaryotic cells.
    • Sequence of e- carrier proteins capable of redox, e- pass through chain = release energy, energy is used to drive chemiosmosis (synthesis of ATP)
    • *NADH and FADH2 are oxidized = large amounts of ATP
    • LOCATION : PLASMA MEMBRANE
