Denoting chemical changes caused by or involving light.

photochemical 

Relating to a chemical change as a result of the absorption of light. Example: The action of light on rhodopsin in the photoreceptors of the retina. See rhodopsin.

photochemical

in laser treatment, the laser light is absorbed and converted into chemical energy.

When the non-photochemical quenching reaches its maximum, any excitation energy still available in the antenna is transferred to the RCIIs; if this transferred energy finds some open RCIIs, it can still be used photochemically, but if it finds all RCIIs close& it will cause oxidative damage to PSII (photoinhibition), as we have discussed before.

Ozone is not the only photochemically produced oxidant, but EPA has decided to focus on it as the primary irritant in smog -- the assumption being that reducing ozone production will simultaneously reduce the production of related photochemical oxidants.
Aduro BioTech has developed two vaccine platforms: the most advanced is the live-attenuated double deleted (LADD) Lm vaccine platform, in which two virulence determinants (actA and inlB) have been deleted from the Lm chromosome, and the second is a photochemically killed but metabolically active (KBMA) vaccine platform.
