Question
1. Which of the following are products of the light reactions of photosynthesis that are
utilized in the Calvin cycle?
A. CO2 and glucose
C. Electrons and H*
B. H20 and O2
D. ATP and NADPH
2. When oxygen is released as a result of photosynthesis, it is a by- product of which of
the following?
A. Chemiosmosis
C. The electron transfer system of PS I
D. The electron transfer system of PS I|
B. Splitting the water molecules
3. Which statement describes the functioning of photosystem I1?
A. The splitting of water yields molecular carbon dioxide as a by- product.
B. The electron vacancies in P680 are filled by electrons derived from water.
C. The excitation is passed along to a molecule of P700 chlorophyll in the
photosynthetic unit.
D. The P680 chlorophyll donates a pair of protons to NADPH, which is thus converted
to NADP*.
4. A scientist suspects that a particular plant contains chloroplasts that lack photosystem
II, even though it is able to live. How could the scientist determine if PS II is missing
from the plant's chloroplast?
A. Test for the presence of sugar
B. Test for the fixation of CO2 in the dark
C. Test the presence of oxygen in light
D. Test for thylakoid presence in the chloroplasts
5. Assumed a thylakoid is somehow punctured so that the interior of the thylakoid is no
longer separated from the stroma. This damage will have the most direct effect on
which of the following processes'?
A. The synthesis of ATP
B. The splitting of water
C. The reduction of NADP*
D. The absorption of light energy by chlorophyll
