Definition
English
:
Photosensitive protein complexes of varied
light
absorption
properties which are expressed in the
PHOTORECEPTOR CELLS
. They are
OPSINS
conjugated with VITAMIN A-based chromophores. Chromophores capture
photons
of
light
, leading to the activation of
opsins
and a biochemical cascade that ultimately excites the
photoreceptor cells.
