Transcript of Photosynthesis
The Light Dependent Reactions
What is light?
radiant energy that travels in waves
the visible spectrum is the wavelength range that humans can see
all of the colors in the visible spectrum make white light
The color you see is being reflected
The other colors are being absorbed
6CO2 + 6H2O + Energy (sunlight) = C6H12O6 + 6O2
Photosynthesis is an endothermic reaction
This means that energy is needed for the reaction to happen
converts solar energy into ATP and NADPH
water is split
oxygen leaves as a waste product
Where do the light reactions happen?
in the photosystems (I and II)
which are in the thylakoid membrane
located in the chloroplast
solar energy (light) is absorbed
water is split (photolysis) -- this is the oxygen we breath
the energy excites electrons (hydrogen from water) in the reaction center
electrons enter an electron transport chain
electrons are accepted from the electron transport chain
soloar energy (light) is absorbed
energy excites electrons further
electrons travel through another electron transport chain
The Light Independent Reactions
also called the Calvin Cycle
ATP and NADPH convert CO2 into glucose (sugar)
Where do the Dark Reactions happen?
in the stroma (fluid part of the chlorplast)
It takes 6 CO2 molecules going through the Calvin Cylcle to make one molecule of glucose (sugar).
What factors affect photosynthesis?
color of light
availability of water and carbon dioxide
6CO2 + 6H2O + ENERGY (SUN) C6H1206 + O6
one carbon from CO2 is added to a five-carbon sugar called ribulose biphosphate
