what is the purpose of photosynthesis
to build carbs
where does photosynthesis occur
in the chloroplast
photautotrophs
use light energy to make organic molecules
heterotrophs
consume organic molecules from other organisms for energy and carbon
chlorophyll
green pigment; absorbs sunlight; reflects back green and yellow light;
stroma
fluid in chloroplast
thylakoid
pancake like structure (increases surface area)
grana
stacks of thylakoids
mesophyll
chloroplasts mainly found in cells of leaf
stomata
pores in leaf (co2 enters / o2 exits)
what kind of light does chlorophyll absorb + reflect
violet-blue/red light; reflect green
photosynthesis formula
6co2 + 6h2o + light → c6h12o6 + 6o2
where does light cycle take place
thylakoid
what is used and split during light cycle
h20
what is water split into during the light cycle
oxygen, two h+, two free e-
how are the electrons and hydrogen moved after being split from water during the light cycle
by the ETC
what is released by the light reaction
oxygen
main idea of light cycle
use solar energy + water to generate ATP & NADPH to provide energy for Calvin Cycle
what is the desired product of the light cycle
ATP & NADPH
what is the calvin cycle also known as
dark reaction
calvin cycle ____ require light
does not
where does calvin cycle take place
stroma
what does calvin cycle use
NADPH, ATP, CO2
what is the product of calvin cycle
G3P (to go on to make glucose, etc)
