Oxygen is a natural acceptor of electrons in the respiratory pathway of aerobic organisms
and in many other biochemical reactions. Aerobic metabolism is always associated with the …

Solar fuel production often starts with the energy from light being absorbed by an assembly
of molecules; this electronic excitation is subsequently transferred to a suitable acceptor. For …

Photoprotection of photosystem II (PSII) is essential to avoid the light-induced damage of the
photosynthetic apparatus due to the formation of reactive oxygen species (= photo-oxidative …

Figures showing species and properties relevant to non-photochemical quenching

Excitons are considered as the basic concept used by describing the spectral properties of
photosynthetic pigment-protein complexes and excitation dynamics in photosynthetic light …

Carotenoids are essential for the survival of photosynthetic organisms [1-6]. They act as
protective devices against irreversible photodestruction of the photosynthetic apparatus …

Carotenoids are, along with chlorophylls, the most abundant pigments found in nature. They
are present in most organisms including humans but can be synthesized only by plants and …

Photosynthesis begins with light harvesting, where specialized pigment–protein complexes
transform sunlight into electronic excitations delivered to reaction centres to initiate charge …

Photosynthesis is one of the most important processes that supplies the energy required for
the survival of all living things. The initial process is the absorption of sunlight by a …

Photosynthesis uses sunlight to convert water and carbon dioxide into biomass and oxygen.
When in excess, light can be dangerous for the photosynthetic apparatus because it can …
