Ap bio test review

  1. 1. AP Biology - October 25th, 2011SWBAT: Demonstrate knowledge of chapters 8, 9 and 10 on the unit test.Warm Up:·Get your pencil sharpened and hand back in your unit pretests, please!
  2. 2. Photosynthesis: CO2 + H2O + light energy C6H12O6 + O2 O2 Cholorplast SugarsCO2 + H2O Mitochondria energy O2 Respiration: C6H12O6 + O2 CO2 + H2O + energy (ATP)
  3. 3. Step 1 of 3: Glycolysis ("Glucose-breaking")C6H12O6 enters the cytoplasm 2 NADH + H are created. These skip step 2 and move directly to step 3. Glycolysis 2 pyruvic acid are created. These move to step 2. 4 ATP are created. . . . . .2 of those ATP are released . . .and 2 of those ATP are reused immediately
  4. 4. Steps 2 and 3: The Krebs Cycle and Electron Transport Chain 2 ATP CO2 Oxygen oxygen water 32 ATP Step 2: Krebs Cycle Step 3: Electron Transport Chainpyruvic acid from glycolysis NADH + H and FADH2 NADH + H from glycolysis made for ETC
  5. 5. Photosynthesis:CO2 + H2O + light energy --> C6H12O6 + O2 Oxygen is made Carbon dioxide is used to make glucose Solar energy starts the process of exciting electrons and moving energy ATP is made for step 2 NADPH+H is made for step 2 STEP 1: STEP 2: Light-Independent Reactions Light Dependent Reactions (Calvin Cycle) WATER is a reactant because it donates an electron (energy) Glucose is MADE using ATP, NADPH+H, Carbon dioxide, and a molecule called RuBP
  6. 6. Chapter Test: 8, 9, 10Know how to compare and contrast several processes, places, and pathways:·Catabolic vs. anabolic pathways·Exergonic vs. endergonic reactions·Allosteric inhibition vs. activation·Cellular respiration vs. photosynthesis·Mitochondria vs. Chloroplast·Krebs Cycle vs. Calvin Cycle·Noncyclic vs. Cyclic Electron Flow·CAM vs. C4 vs. C3 plants·Substrate-level vs. Oxidative phosphorylation·Photorespiration vs. Photosynthesis·Aerobic vs. Anaerobic Respiration
  7. 7. Cyclic Vs. Noncyclic (Light Rxs of Photosynthesis)Noncyclic = normal -- creates ATP, NADPH and oxygen Longer process - uses Photosystem 2, then photosystem 1Cyclic kicks in when Calvin Cycle needs more ATP to proceed Uses photosystem 1 only and makes ONLY ATP Does NOT make NADPHSubstrate-Level Vs. Oxidative Phosphorylation
  8. 8. Cellular Respiration(Fermentation)Photosynthesis
  9. 9. CAM - stomata/night vs day actionC4 - mesophyll vs. bundle sheaths - cellular separation of photosynthesis (carbon fixation intwo different types of cells)CAM and C4 are used to minimize photorespirationCarbon dioxide is no longer brought in because of high levels of oxygen -- Rubisco can pick upeither carbon dioxide or oxygen as a substrate--------------------------------------------------------------------------C3 - normal photosynthesis
  10. 10. Two Types of Cell Resp: Anaerobic Vs. AerobicNORMAL (for humans) = aerobic We are facultative anaerobes - we go in to anaerobic (fermentation) when we dontget enough oxygen to proceed with krebs/ETC Lactic acid formation (fermentation) occurs so ATP can be created, NADH gets cycledback to NAD+. ATP is made via substrate-level phosphorylation.Obligate anaerobes normal = anaerobic
