Unregulated chlorophyll without photosynthesis generates toxic reactive oxygen species
the verdict
SUPPORTED
the evidence backs this
confidence 75/100
Unregulated chlorophyll and its derivatives act as photosensitizers that generate toxic reactive oxygen species (ROS) when exposed to light, necessitating strict metabolic regulation.
