Photosynthesis Flashcards
Photosynthesis equation
CO2 + light + H2O = C6H12O6 + O2
Photosynthesis
Carbon is reduced
In chloroplasts
Energy is stored in food
Used by heteroautotrophs to make food and get energy
Two parts
Light reactions
Calvin cycle
Light reactions
Energy of light is captured
Water is split into H and O2
Calvin Cycle
CO2 is used to build sugars
Carbon fixation
Turning CO2 into sugars
Energy comes from ATP and NADPH from light reaction
In stroma
First phase of calvin cycl
Reduction
2 phase of calvin
Energy is added to molecules
RuBisCo
Enzyme- fines carbon
RuBP
Substrate to carbon fixation
5 carbon thing that CO2 is added to
Product of Calvin cycle
3GP (2 make one glucose)
Photo system ll
P680
Chlorophyll takes photos and H2O is split into H and O the energy of light knocks electrons off of chlorophyll
Electrons travel through ETC and H+ is moved out of the thylakoids causing ATP synthase to make ATP electrons are passed to photo system l
Photo system l
P700
More light energy (photons) and to another ETC and NADP+ 2e and H+ becomes NADPH
