Electron paramagnetic resonance
Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a method for studying materials with unpaired electrons.
New!!: Pheophytin and Electron paramagnetic resonance · See more »
Electron transport chain
An electron transport chain (ETC) is a series of complexes that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.

P680
P680, or Photosystem II primary donor, (where P stands for pigment) refers to either of the two special chlorophyll dimers (also named special pairs), PD1 or PD2.

Photosynthesis
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities (energy transformation).

Photosynthetic reaction centre
A photosynthetic reaction centre is a complex of several proteins, pigments and other co-factors that together execute the primary energy conversion reactions of photosynthesis.
New!!: Pheophytin and Photosynthetic reaction centre · See more »
Photosystem
Photosystems are functional and structural units of protein complexes involved in photosynthesis that together carry out the primary photochemistry of photosynthesis: the absorption of light and the transfer of energy and electrons.
New!!: Pheophytin and Photosystem · See more »
Photosystem II
Photosystem II (or water-plastoquinone oxidoreductase) is the first protein complex in the light-dependent reactions of oxygenic photosynthesis.

Plant
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae.

Plastoquinone
Plastoquinone (PQ) is an isoprenoid quinone molecule involved in the electron transport chain in the light-dependent reactions of photosynthesis.

Purple bacteria
Purple bacteria or purple photosynthetic bacteria are proteobacteria that are phototrophic, that is, capable of producing their own food via photosynthesis.

Quinone
The quinones are a class of organic compounds that are formally "derived from aromatic compounds by conversion of an even number of –CH.
