site of PSN, between 2 membranes(inter membrane) |
|
|
granum is: |
stack of thylakoids |
|
|
thylacoids are: |
one part of a granum |
|
|
overall reaction of PSN |
6 CO2+12 H2O+ light energy --> C6H12O6+ 6 O2+ 6 H2O |
|
|
simplified reaction of PSN |

|
|
what are the two stages to photosynthesis? |
photochemical, biochemical/calvin cycle |
|
|
where does a photochemical reaction take place? |
thylakoid membrane |
|
|
where does the biochemical/calvin cycle take place? |
the stoma |
|
|
what type of reaction is photosynthesis? |
endergonic (we are building up) |
|
|
characteristics of solar energy |
shorter the wave length, higher the energy |
|
|
what is photolysis? |
when light splits water |
|
|
what does PQ stand for? |
plastoquinone |
|
|
what does PC stand for? |
plastocyanin |
|
|
what does FE stand for? |
ferredoxin |
|
|
what is NADP+? |
electron acceptor |
|
|
what is NADPH? |
an electron carrier |
|
|
what is chemiosmosis? |
the process of using energy in the form of a chemical gradient across a membrane to drive cellular work |
|
|
what is ATP synthase complex? |
H+ ions travel through this from the thylakoid space to the stroma |
|
|
what do you need to start a biochemical reaction? |
NADPH and ATP |
|
|
is the calvin cycle anabolic or catabolic? |
anabolic |
|
|
why is the calvin cycle anabolic? |
carbon enters the cycle in the form of CO2 and leaves in the form of a sugar. |
|
|
is the calvin cycle endergonic or exergonic? |
endergonic |
|
|
why is the calvin cycle endergonic? |
it uses ATP created in the light reactions and NADPH as a source of high energy electrons |
|
|
what are the three stages of the calvin cycle? |
carbon fixation, reduction, regeneration |
|
|
what happens in phase one of the calvin cycle? |
it uses the enzyme rubisco to fix carbon to RuBP
|
|
|
what happens in phase two of the calvin cycle? |
makes G3P(sugar) |
|
|
what happens in phase three of the calvin cycle? |
regeneration of the CO2 acceptor (RuBP) |
