A photosynthetic reaction centre is a complex of several proteins, pigments and
other co-factors ... These electron transfer steps are the initial phase of a series of
energy conversion reactions, ....
Photosynthesis, like respiration, is a redox (oxidation-reduction) process-Water
molecules are split apart by oxidation, which means that they lose.
The reduction potential E for a complete redox reaction must be positive to yield
energy for ... The electrons are ultimately transferred to NADH or NADPH.
Similar to the way the reactions of aerobic cellular respiration rely on oxidation-
reduction reactions, electrons produced during photosynthesis are transferred to
We know that redox reactions occur in the direction of stronger to weaker
oxidizing ... In nonradiative decay, the energy of an excited electron can be
transferred to another ... It ultimately passes its electrons along to NADP<sup>+</sup> to form
The photosynthesis reactions can be broken down into two components: ... The
electrons are passed through a chain of oxidation-reduction reactions. ...
molecules and ultimately end up transferred to to a molecule called
into chemical energy by a series of reactions that give rise to a coupled flow of
electrons ... PQ ultimately transfers electrons to a terminal electron acceptor by ...
in these reactions is PQ, the most abundant redox component in photosynthetic.
Aug 26, 2004 ... Photosynthesis is light-driven redox chemistry. Molecular ... The primary event is
light-driven electron transfer — a redox reaction — and it sets in motion a chain of
electron transfers upon which all life ultimately depends.
Dec 30, 2010 ... Reduction-oxidation (redox) reactions are an essential part of cell ... However,
the electron transfer within a redox couple needs to be strictly ... in plant cells
ultimately originates from the light-driven electron transfer from water ...
Photosynthesis by oxygen-evolving organisms depends on the interplay of two ...
Photosystem II Transfers Electrons from Water to Plastoquinone and Generates a
.... by photosystem I is a simple one-electron oxidation-reduction reaction.
