2. Define autotrough and heterotrough Autotrough: makes its own food. Autotrough: makes its own food. Heterotrough: eats food. Heterotrough: eats food.

3. Write the equations for photosynthesis and cellular respiration. Photosynthesis Photosynthesis 6CO 2 + 6H 2 O LIGHT C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O LIGHT C 6 H 12 O 6 + 6O 2 Carbon dioxide + water light glucose + oxygen Carbon dioxide + water light glucose + oxygen Cellular Respiration Cellular Respiration C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O Glucose + oxygen carbon dioxide + water Glucose + oxygen carbon dioxide + water They are opposite reactions!! They are opposite reactions!!

4. What is a thylakoid? A membrane system found within chloroplasts that contains the components for photosynthesis A membrane system found within chloroplasts that contains the components for photosynthesis

5. From what molecule do plants take oxygen from? Water: H 2 O Water: H 2 O

6. What are the reactants of cellular respiration? Glucose and oxygen Glucose and oxygen

7. Contrast anaerobic vs. aerobic. Anaerobic = without oxygen Anaerobic = without oxygen Aerobic = with oxygen Aerobic = with oxygen

8. When electrons of a chlorophyll molecule a raised to a higher energy level, where do they go? They enter an electron transport chain. They enter an electron transport chain.

9. The final electron acceptor in aerobic respiration is… oxygen oxygen

10. During which phase of cellular respiration is carbon dioxide produced? The Krebs Cycle The Krebs Cycle
