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. Photosynthesis Basics Importance of Pigments Light Reaction
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

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

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

8. Cell Respiration Basics Glycolysis Citric Acid/Krebs Cycle
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

9. 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!

10. 2. Glycolysis 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

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

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

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