A CONCEPT OF THREE LIGHT REACTIONS IN PHOTOSYNTHESIS BY GREEN PLANTS
AUTOR(ES)
Knaff, David B.
RESUMO
It has generally been accepted that plant photosynthesis involves two light reactions, one that proceeds best in short-wavelength light and is identified with oxygen evolution (System II) and another that proceeds best in long-wavelength light and is identified with a cycle electron flow (System I). This paper presents a concept of three light reactions in photosynthesis, based on new evidence that System II comprises two rather than one short-wavelength light reaction. These appear to operate in series and to be connected by an electron transport chain peculiar to System II. Parallel to System II is the long-wavelength light reaction of System I.
