Light absorption
Which pigment is poor at absorbing green wavelengths?
Chloropyll
What are the two main inputs of photosynthesis in the light-dependent reactions?
Light energy and water
Which photosystem is included in this cycle?
PSI
What is the main input and output of the Calvin Cycle?
CO2 -> carbohydrate
Where does the initial electron come from to start photosynthesis?
Water
What are the chlorophyll molecules that neighbor the reaction center called?
Antenna chlorophyll
Where does an electron get excited in the photosystem?
How is ATP produced? (What method)
Proton gradient
What two molecules are needed as additional inputs in the calvin cycle and ultimately end up getting reduced/oxidized?
NADPH and ATP
What enzyme catalyzes the reaction between RuBP and CO2?
Rubisco
Where are accessory pigments found?
Thylakoid membrane
When/where do the two inputs of light enter this reaction?
PSII and PSI
If this cycle is used, where will the electron loop back around to the Pq -> Cytochrome Complex -> Pc chain?
Fd
Instead of going to NADP+ reductase, the electron will go back through ETC.
What reduced the two triose phosphate molecules in step 2 of the calvin cycle?
NADPH
Where are excess carbohydrates stored?
Starch
Where does light energy ultimately travel to within PSII?
Reaction center
What enzyme creates NADPH at the end of this reaction?
NADP+ Reductase
What are the names of the locations on the inside and outside of the thylakoid membrane?
Lumen inside
Stroma outside
What are the three steps of the Calvin Cycle?
Carboxylation, reduction, regeneration
What other process is used by plants to consume energy and release CO2?
Photorespiration
When the reaction center accepts the donated electron, it becomes ____________.
Reduced
What are the three locations (molecules/stations) does an electron travel through in between PSII and PSI?
Pq -> Cytochrome Complex -> Pc
Why is this cycle sometimes used instead of noncyclic reactions?
If too much NADPH is being produced and only ATP is needed.
What is made at the end of step three and how much of it is regenerated in the cycle?
Six triose molecules produced
Only 1 withdrawn
5C RuBP molecule back in the cycle to combine with CO2
If the reaction center breaks a water molecule, what are the three elements released, and where do each of them go?
Electron -> goes through noncyclic and cyclic reactions
Oxygen -> released
H+ -> creates proton gradient
