  1. Bioenergetics Foldable Fold 3 pieces of paper as follows and label: How do Cells Make and Produce Energy? How do Cells Release Stored Energy?

  2. How do Cells Make and Produce Energy?(Part 1: Photosynthesis Foldable) • Photosynthesis Basics • Importance of Pigments • Light Reaction • Dark reaction • Comparison of Photosynthesis & Respiration

  3. 1. Photosynthesis Basics Define: A process by which an autotroph (ex. plant) uses the sun’s energy to make food (simple sugar= glucose) Equation: 6CO2 + 6H2O + sunlight  C6H12O6 + 6O2 PHOTOSYNTHESIS • Phases: • Light Reaction • Dark Reaction Simplified: Production of simple sugar (glucose = C6H12O6)

  4. 2. Importance of Pigments • Chloroplasts  contain pigments • Pigments – absorb and reflect light • Chlorophyll, most common pigment, absorbs all color of light except GREEN, it reflects it! • Fall leaves  no chlorophyll Stacks contain pigment that absorb light

  5. 3. Light Reaction • Depends on light • End Product = ATP used in dark reaction

  6. AKA the “Calvin Cycle” Does not depend on light End Result = GLUCOSE 4. Dark Reaction

  7. How do Cells Release Stored Energy?(Part 2: Cellular Respiration Foldable) • Cell Respiration Basics • Glycolysis • Citric Acid/Krebs Cycle • Electron Transport Chain • Comparison of Photosynthesis & Respiration

  8. 1.Cellular Respiration Basics Equation: C6H12O6 + 6O2  6CO2 + 6H2O + ATP Define: A process by which mitochondria breaks down food to produce energy Cellular Respiration • Stages: • Glycolysis • Citric Acid/Krebs Cycle • Electron Transport Chain * All living things undergo cell respiration, even plants!

  9. Does not require oxygen (anaerobic) Series of chemical reactions that break down glucose into 2 pyruvic acid molecules Starts with 2 ATP Produces 4 ATP Net ATP = 2ATP * Not most effective way to produce energy 2. Glycolysis

  10. 2nd step of respiration only if oxygen is present 3. Citric Acid or Krebs Cylce Every turn produces 1 ATP, 2 CO2

  11. Step #3 of Cell Respiration only if oxygen is present MOST EFFECTIVE way to produce ATP End result = 32 ATP 4. Electron Transport Chain

  12. Fermentation – anaerobic process (no oxygen) by which food is broken down Types: Lactic Acid Alcoholic Cell Respiration in Review(Glue to Back)

  13. 5. Comparison of Photosynthesis & Respiration Word Bank: food production, anaerobic, aerobic, ATP production, light reaction, energy release, glycolysis, Calvin cycle, light, water as reactant, water as product, carbon dioxide reactant, carbon dioxide product, glucose reactant, glucose product, citric acid, electron transport chain, fermentation
