| 11. | Per the radical pair mechanism photopigments absorb a photon, which elevates it to the singlet state.
|
| 12. | It is yet unknown how the animals that gain a new photopigment are perceiving the new color.
|
| 13. | The human peripheral retina senses light at high intensities that is best explained by four different photopigment classes.
|
| 14. | "' Photopigments "'are unstable pigments that undergo a chemical change when they absorb light.
|
| 15. | The reaction of this single photopigment will give the same quanta for 400 nm light and 700 nm light.
|
| 16. | Carotenoids and photopigments both indirectly act as photo-protective pigments, as they quench oxygen free-radicals.
|
| 17. | The xanthophyll cycle takes place, along with other photopigment reactions, in the membranes of thylakoids within chloroplasts.
|
| 18. | Photopigments exist as transmembrane proteins within these disks, which provide more surface area for light to affect the pigments.
|
| 19. | Cryptochromes, a class of photopigments known from plants and related to photolyases, have been suggested as receptor molecules.
|
| 20. | The encoded protein is called red cone photopigment or long-wavelength sensitive opsin ( LWS opsin or L opsin ).
