Question 1.
What is photo-phosphorylation?
Show hintHide hint
Think about how energy is converted during photosynthesis.
Question 2.
Name one product of non-cyclic photo-phosphorylation.
Show hintHide hint
Remember, non-cyclic involves two photosystems.
3Question 3.
What is a primary product of cyclic photophosphorylation?
- ATP
- NADPH
- Oxygen
Show hintHide hint
Remember that cyclic relates to recycling of electrons in PSI.
4Question 4.
True or False: Non-cyclic photo-phosphorylation produces both ATP and NADPH.
- True
- False
Show hintHide hint
Consider what each photosystem does.
Question 5.
If a plant undergoes photosynthesis in the dark, how would its ATP synthesis be affected? Explain your answer.
Show hintHide hint
Consider the role of light in activating the photosystems.
Question 6.
Describe how the absence of water would affect non-cyclic photo-phosphorylation and the plant's overall energy production.
Show hintHide hint
Think about what happens to the electron flow if water is absent.
