Photosynthesis: Acquiring Energy from the Sun
Review
Photosynthesis
takes place in the
leaves
of plants to transform light energy into the chemical energy of
via
pigments
.
This process involves two steps: the light-
reactions
and the light-
reactions (Calvin cycle).
Light-dependent reactions
Groups of pigments are embedded in
membranes
and organized into
to capture light energy in

Two
electron
transport
systems
harvest the energy in the electrons to produce

The
Calvin
cycle uses products of the light-dependent reactions,
