Photosynthesis
Conversion of light energy from the sun into chemical energy.
Photosynthesis Equation
6CO2 + 6H2O + light --> C6H12O6 + 6O2
Light Dependent Reactions
reactions of photosynthesis that use energy from light to produce ATP and NADPH
Chloroplasts
organelles that carry out photosynthesis
Thylakoid
saclike photosynthetic membranes found in chloroplasts
Grana
Stacks of Thylakoids (B)
Stroma
fluid portion of the chloroplast; outside of the thylakoids
Electron Transport Chain
a series of proteins in the membrane of the thylakoid
Photosystem 1
the electrons are re-energized by light energy and used to make NADPH. 2nd photosystem in ETC.
Photosystem 2
Uses light energy to split water. 1st photosystem in the light dependent reactions.
ATP and NADPH
high energy products made by the light reactions and used in the Calvin cycle
ATP synthase
makes ATP by adding phosphate groups to ADP
Water
Needed for Light dependent reactions to take place
Light
Required for the light dependent reactions to take place.
products of light reactions
ATP and NADPH
reactants of light dependent reactions
sunlight and water
light-dependent reactions
H20 + Sunlight ----> ATP + NADPH
