
1. All Plants (Plant Kingdom)

2. Algae (Protist groups: red algae,
brown algae, green algae, diatoms,
dinoflagellates)

3. Cyanobacteria (Bacteria Kingdom)
1. water is used up and oxygen is
produced
 2. Photosystem II captures sunlight and
absorbs electrons from splitting water
to replace electrons from chlorophyll
 3. Photosythem I also captures sunlight
and carries electrons from proteins
 4. Electron is captured by NADP+ along
with H+ ions to form higher energy
NADPH.

5. ATP is produced by H+ ions moving
through an enzyme called ATP
Synthase
 6. Light Dependent Reactions occur in
green parts of a plant = leaves (and
not in the roots underground)
 Also: algae and cyanobacteria contain
pigments to absorb sunlight and
conduct photosynthesis (Do
cyanobacteria have chloroplasts?)

1. The 2 high energy molecules
produced in Light Dependent Rx are
used up: ATP and NADPH
 2. CO2 is used up
 3. One organic sugar, glucose, is
produced for each 6 CO2 used.
 4. RuBP is regenerated at the end of
each cycle and ready for the next CO2


1. source of ALL atmospheric oxygen
(Why is this important?)

2. source of all organic molecules,
starting with glucose, a carbohydrate
(Why is this important?)

3. mitigates global warming by
absorbing CO2 (Why is this important?)
