Using intact thylakoid membrane samples, we show how conventional TA kinetic and spectral analyses enable the determination of the appropriate wavelength and time delay for snapshot TA experiments.
As an example, we show how the chlorophyll-carotenoid charge transfer and excitation energy transfer mechanisms can be monitored based on signals corresponding to the carotenoid (Car) radical cation and Car S excited state absorption, respectively.

Additional research articles see Four distinct trimeric forms of light-harvesting complex II isolated from the green alga Chlamydomonas reinhardtii Light-harvesting complex II (LHCII) absorbs light energy and transfers it primarily to photosystem II in green algae and land plants.ATP, from both cyclic and noncyclic photophosphorylation, and reduced NADP jointly constitute the assimilatory power for the conversion of CO 685 nm).Cyclic photophosphorylation in chloroplasts involves a System I photoreaction.Noncyclic photophosphorylation is widely held to involve a collaboration of two photoreactions: a short-wavelength photoreaction belonging to System II and a long-wavelength photoreaction belonging to System I.Recent findings, however, indicate that noncyclic photophosphorylation may include two short-wavelength, System II, photoreactions that operate in series and are joined by a “dark” electron-transport chain to which is coupled a phosphorylation site.Historically, the role of light in photosynthesis has been ascribed either to a photolysis of carbon dioxide or to a photolysis of water and a resultant rearrangement of constituent atoms into molecules of oxygen and glucose (or formaldehyde).The discovery of photophosphorylation demonstrated that photosynthesis includes a light-induced phosphorus metabolism that precedes, and is independent from, a photolysis of water or CO) serves as an electron donor for the reduction of NADP by an enzymic reaction that is independent of light.The redox rhythm disappeared when transcription/translation of clock genes is defunctionalized, indicating that the transcription/translation controlled by a core Kai ABC oscillator generates the circadian redox rhythm.Importantly, the amplitude of the redox rhythm at a constant light condition was large enough to affect the Kai ABC oscillator.The absorption and fluorescence spectra were also similar, although the peak positions differed slightly.These results indicate that this green alga contains four types of LHCII trimer with different biochemical and spectroscopic features.
