Photosynthesis & Cellular Respiration Objective: 9B - Compare the reactants & products of photosynthesis & cellular respiration in terms on energy & matter 4B - Investigate and explain cellular processes, including homeostasis, energy conversions, transport of molecules, and synthesis of new molecules

1. Define Autotroph & Heterotroph Autotroph – makes it’s own food Example: Plants Heterotroph – consumes other organisms for food Example: Animals

Adenosine Triphosphate 2. What does ATP Stand for? Adenosine Triphosphate 3. Define ATP? Biological molecule that provides cellular energy

4. Draw & label an ADP & ATP molecule below.

5. What is the main difference between these 2 molecules? ATP has an extra phoshate 6. When is the energy stored in ATP released? when the bond is broken

7. Write the EQUATION FOR PHOTOSYNTHESIS. REACTANTS PRODUCTS LIGHT ENERGY 6CO2 + 6H2O C6H12O6 + 6O2

8. Which organelle is responsible for photosynthesis? chloroplast 9. Draw a picture of what a chloroplast looks like.

10. Which colors of light are absorbed by chlorophyll a? Violet & orange 11. Which colors of light are absorbed by chlorophyll b? Blue & yellow

12. Which color of light is reflected? green 13. Why are leaves green? Chlorophyll reflects green light

14. Write the EQUATION FOR CELLULAR RESPIRATION REACTANTS PRODUCTS C6H12O6 + 6O2 6CO2 + 6H2O ATP ENERGY

15. Which organelle is responsible for respiration? mitochondria 16. Draw a picture of what a mitochondria looks like.

17. What is the molecule used by the cell for energy? ATP

The products of one are the reactants of the other Aerobic More oxygen allows more ATP to be made 20. Compare the photosynthesis & respiration equation? The products of one are the reactants of the other
