1. Bioenergetics Photosynthesis
Test Review

2. What factors affect photosynthesis?
Temperature, light intensity, water

3. Describe how the energy transformations involved in photosynthesis are related to energy transformations in cellular respiration.
Both include reactions that transform energy. The products of one are the reactants of the other- photosynthesis stores energy in sugars to be used in the process of cellular respiration.

4. Which molecule in plant cells first captures radiant energy from sunlight?
chlorophyll

5. What energy transformation occurs in the chloroplast?
Light to chemical potential

6. Define photosynthesis.
the process by which the energy of light, carbon dioxide, and water are converted into glucose and oxygen

7. Where does photosynthesis take place?
In the chloroplast
light dependent- thylakoids
light independent- stroma

8. What is the overall equation for photosynthesis?
carbon dioxide + water + light  glucose + oxygen

9. What is the function of chlorophyll in photosynthesis?
captures energy of sunlight

10. What are the two stages of photosynthesis? Where does each take place?
Light dependent reaction- takes place in the thylakoids
Light independent reaction (Calvin Cycle)- takes place in the stroma

11. In what ways are photosynthesis and cellular respiration similar?
Both include reactions that transform energy. They both involve organic and inorganic molecules.

12. What is the name of the first stage of photosynthesis?
Light dependent reaction

13. Explain the light dependent reactions and the light independent reactions.
light dependent- H2O and light makes ATP and Oxygen.
light independent- carbon dioxide plus the ATP from the light dependent reaction used to make sugars.

14. What is another name for the light independent stage of photosynthesis?
Calvin Cycle

15. What are the differences between cellular respiration and photosynthesis?
Photosynthesis produces glucose and oxygen from water, carbon dioxide and light. Cellular respiration breaks down the glucose using oxygen to release energy, carbon dioxide, and water.
