The Photosynthesis Quiz II tests your knowledge about the photosystems involved in the light-dependent reactions of photosynthesis.
1. Where are the photosystems located in photosynthetic plants?
a.Free floating in the stroma
b.Embedded in the thylakoid membrane
c.Linked to the outside of the grana
d.Linked to the outside of the cell wall
2. What is the order of events for the light-dependent reactions?
a.Stroma absorb sunlight, ATP and NADPH formation, electrons replaced in pigments
b.Protons added to pigments, pigments absorb sunlight, ATP and NADPH formation
c.ATP and NADPH formation, pigments absorb sunlight, electrons replaced in pigments
d.Pigments absorb sunlight, ATP and NADPH formation, electrons replaced in pigments
3. Which of the following statements are true about photosystems?
a.Each has a reaction center
b.A membrane may have thousands of them
c.Each contains 200 to 300 pigment molecules
d.They can absorb a photon
4. The molecule that traps the excitation energy and gives up electrons for photosynthesis is called:
a.Chlorophyll a
b.Photon distributor
c.Reaction center
d.Photosystem electron acceptor
5. Which statement(s) best describe(s) an electron transport system (ETS)?
a.A unidirectional chain of enzymes and coenzymes that can pass electrons one way
b.A bidirectional chain of enzymes and coenzymes that can pass electrons either way
c.A free-floating soup of enzymes, coenzymes, and cofactors in the cytoplasm
d.An organized, sequential array of enzymes, coenzymes, and proteins in a cell membrane
6. What does the term "cyclic" mean in reference to photosystem I?
a.Electrons are passed in circles around the reaction center until they hit it
b.The photons of light circle through the grana until they find a reaction center
c.Once the ATP formation has been done by the ETS the electron returns to PS I
d.The electron that started by the splitting of water is made back into water
7. Photosystems I and II sometimes "swap" their reaction centers.
a.True
b.False
8. Which of the following are true about photosystem II?
a.It begins the non-cyclic pathway of ATP synthesis
b.It has P680 as its reaction center
c.It replaces its lost electron through photolysis of water
d.It is the site of NADH formation
9. The excited electrons from photosystem II get even more excited in photosystem I because of the photons bombarding the P700 reaction center.
a.True
b.False
10. If you see bubbles coming off of underwater plants, what are you seeing?
a.Oxygen bubbles from reactions in photosystem I
b.Oxygen bubbles from reactions in photosystem II
c.Oxygen bubbles from reactions in the non-cyclic pathway of photosynthesis
d.Oxygen bubbles from photolysis
11. Why are electron transport systems important in photosynthesis?
a.They reduce NADP+ to NADPH for later reducing power in syntheses
b.They reduce NAD+ to NADH for later reducing power in syntheses
c.They convert ATP into ADP which provides a store of energy
d.They convert ADP into ATP which provides a store of energy
12. Which of the following is(are) not true?
a.Excited electrons from PSII are higher in energy than excited electrons from PSI
b.Excited electrons from photolysis are higher in energy than excited electrons from PSI
c.Excited electrons from PSI are higher in energy than excited electrons from PSII
d.Electrons are higher in energy before they enter the ETS than after they leave it

  This quis is not stupid mr Byrnes... if you are ashamed because u failed u will just have to learn photosynthesis :)
By: Professor McSnobbenheimer on Sep 16, 2009
  Yes, yes quite
By: Bob on Nov 24, 2008
  This is a rather difficult quiz, especially if you know nothing about the photosystems...
By: Leah Byrnes on Nov 13, 2008
  What do you call this quiz? STUPID!
By: Syazmin on Oct 30, 2008
  I did not read the chapter before i did this test.the questions are quite easy(if i have read it before-handed)
