Photosynthesis Flashcards
What is the formula for photosynthesis
6CO + 12H2O + photons —>. C6H12O6 + 6O2 + 6H2O
What are the two main parts of photosynthesis
Light dependent, light independent
What is carbon fixation
The process of taking carbon from CO2 and attaching it to an organic molecule
Dense fluid within a chloroplast
Stroma
The space within the thylakoid
Thylakoid lumen
What does photo system 2 do
Uses photons to excite electrons then uses an electron transport chain to pump H+ ions into the thylakoid lumen.
What is photophosphorylation
The use of light to attach phosphate to ADP
What are the biproducts of the light reactions
ATP, NADPH
Where does the original electron come from in photosynthesis
H2O
What does photo system 1 do
Reduces NADP+ to NADPH
Where do the light independent reactions take place
In the stroma
Organism that uses light energy to synthesize organic molecules
Photoautotroph
Mesophyll
Interior leaf tissue
Stomata
Pores on the leaf that where CO2 enters and O2 exits
Action spectrum
Profile of the relative effectiveness of different wavelengths of radiation in driving photosynthesis
The flow of electrons through photo systems and other molecular components
Linear electron flow
P680
Photo system 2
P700
Photo system 1
How many phases are in the calves cycle
3
Phase one of the carbon system is also known as
carbon fixation
Carbon fixation and Calvin cycle occur in different types of cells at the same time
C4 photosynthesis
Input - 3CO2, 6ATP
Output -6 ADP
Phase one of the calvin cycle
Phase 2 of the calvin cycle input and output
Input - 6 NADPH.
Output- NADP+ , 6 phosphates, G3P
CAM photosynthesis
Carbon fixation and Calvin cycle occurs in the same cells at different times (day and night)
