Postharvest Imaging of Chlorophyll Fluorescence from Lemons Can Be Used to Predict Fruit Quality
We demonstrate the feasibility of assaying and predicting post-harvest damage in lemons by monitoring chlorophyll (Chl) fluorescence. Fruit quality was assayed using a commercial instrument that determines pho...

Photosynthetic Activity During the Cell Cycle of the Green Alga Scenedesmus Quadricauda
Synchronous cultures of algae have been repeatedly shown to exhibit a periodic modulation of the metabolic activity. In algal cells synchronized by light/dark periods, the photosynthetic activity exhibits a ma...

Functional size of Photosystem II determined by radiation inactivation
The functional size of Photosystem II (PS II) was investigated by radiation inactivation. The technique provides an estimate of the functional mass required for a specific reaction and depends on irradiating s...

The Electrogenic Reaction and Proton Release During Quinol Oxidation by the Cytochrome b/F Complex
The central element in electron transport between photosystem II and photosystem I is the cytochrome b/f complex that oxidizes plastoquinol and reduces plastocyanin. The complex includes four redox components, th...

Inhibition of Electron Transfer in the Cytochrome b/f Complex By NQNO and DBMIB: Evidence for Two Quinone Binding Sites
The oxidation of plastoquinol by the cytochrome b/f complex is the slowest step in light-saturated photosynthetic electron transport. The reaction involves the removal of two electrons and two protons from plasto...

Recovery Time of Physiologically Inactive Photosystem II Reaction Centers Measured by the Electrochromic Absorbance Change at 515nm
Presently a controversy exists in the literature concerning the ratio of PSII to chlorophyll in thylakoid membranes. The techniques used to measure this ratio are at the crux of the disagreement. Whereas techn...

Energy Transfer and Energy-Coupling Processes
Cytochrome bc complexes acting as quinol-cytochrome c (or plastocyanin) oxi-doreductases are central constituents of many electron transport chains (Ort, Chap. 4; Dutton, Chap. 5, this Vol.). Although mitochondri...
