6. In which steps of photosynthetic electron flow from water to NADP+ is
energy input required - ANSWER - P680 --> Pq (plastoquinone)
- P700 --> Fd (ferredoxin)
7. In which steps of photosynthetic electron flow from water to NADP+ is
energy input NOT required - ANSWER - Water --> P680+

, 8. Autotrophs - ANSWER Self-feeders; plants, bacteria, etc.
9. Heterotrophs - ANSWER Eat others in order to obtain nutrients; animals,
humans, etc.
10.Thylakoid - ANSWER A flattened membrane sac inside the chloroplast, used
to convert light energy to chemical energy.
- Photosystems I and II, ATP Synthase, and Electron Transport Chain
are contained here
11.______ phosphoroylates ADP - ANSWER ATP Synthase
12._____ releases energy that is used to pump hydrogen ions from the stroma
into the thylakoid compartment. - ANSWER Electron Transport Chain; The
energy released as electrons are passed along the electron transport chain is
used to pump protons into the thylakoid compartment.
13._____ splits water into 1/2 O2, H+, and e- . - ANSWER Photosystem II
14.Energized electrons from ____ enter an electron transport chain and are then
used to reduce NADP+. - ANSWER Photosystem I
15.Chlorophyll can be found in _____. - ANSWER The Photosystems
16.Assume a thylakoid is somehow punctured so that the interior of the
thylakoid is no longer separated from the stroma. This damage will have the
