The Hill reaction, its elucidation, and significance is briefly described. Hill oxidants, the role of the methemoglobin reducing factor and its relation to ferredoxin, and the part played by chloroplast envelopes are discussed.

The results showed that NADP photoreducing activity of the reconstituted system was comparable to the original physiological activity, which proved that the FNR—connectein complex, which binds to a specific site on the surface of thylakoid membrane, is functionally responsible for NADPPhotoreduction in chloroplasts.
Photosynthesis and the Charles F. Kettering Research Laboratory
A review of the establishment and subsequent demise of the Charles F. Kettering Research Laboratory (in Yellow Springs, Ohio) is presented here.

The contributions of Dick Jensen and Al Bassham and their colleagues and I, made to the achievement of this goal and the way in which it led to a better understanding of the role of inorganic phosphate in its relation to the movement of metabolites across chloroplast envelopes are described.
Period-four oscillations of the flash-induced oxygen formation in photosynthesis*
The earlier researches that led to the discovery of the period-four oscillations of the flash-induced oxygen formation are presented and the background of the classical model proposed by Bessel Kok is included.
Evolution of the Z-scheme of photosynthesis: a perspective
The concept of the Z-scheme of oxygenic photosynthesis is in all the textbooks. However, its evolution is not. We focus here mainly on some of the history of its biophysical aspects. We have
Discoveries in Oxygenic Photosynthesis (1727–2003): A Perspective
This history begins with the observation of the English clergyman Stephen Hales that plants derive nourishment from the air and includes the definitive experiments in the 1960–1965 period establishing the two-photosystem and two-light reaction scheme of oxygenic photosynthesis.
Binding Properties of Photosynthetic Herbicides with the QB Site of the D1 Protein in Plant Photosystem II: A Combined Functional and Molecular Docking Study
Analysis of OJIP chlorophyll fluorescence kinetics and PSII activity assays performed on thylakoid membranes isolated from pea plants with molecular docking using the high-resolution PSII structure recently solved from the same plant showed for terbuthylazine, metribuzin and diuron the highest affinity for the D1 QB site, with the latter two molecules forming hydrogen bonds with His215.
Dark oxidation of water in soils
We report the release of oxygen (O2) under dark conditions in aerobic soils. This unexpected process is hidden by respiration which constitutes the dominating reversal O2 flux. By using H2 18O in


Pyocyanine and Phosphorylation with Chloroplasts.
The process of formation of oxygen by illuminated chloroplast preparations in presence of added Hacceptors resembles the converse of the process of the oxidation of H-donors by oxygen with the

Red Drop and Role of Auxiliary Pigments in Photosynthesis.
The so-called chromatic transient, as observed after the replacement of illumination with light at 700 mu by illumination weith a shorter-wave light giving the same steady yield of photosynthesis, has the same action spectrum as the Emerson effect.
Oxygen Evolved by Isolated Chloroplasts
The hæmoglobin method, originally used by Hoppe-Seyler to demonstrate oxygen from green plants, has been applied to study the oxygen evolution of isolated chloroplasts exposed to light.

The major theme of my work in photosynthesis has been electron transport in green plant thylakoids. In particular, we investigated the properties and the role of the NADP-reducing flavoprotein and
When mice were given the specific antimetabolite of serotonin, viz., 1-benzyl-2,5-dimethylserotonin or BAS, followed by 5-hydroxytryptophan, the serotonin content of their brains was markedly increased, an indication that the excess serotonin in the brain was pharmacologically active.
Studies with the Reconstituted Chloroplast System
Photosynthetic carbon assimilation by isolated chloroplasts was first demonstrated by Arnon et al. in 1954. Work in the same laboratory also showed that the amount of CO2 fixed was diminished by

CO2-dependent Oxygen Evolution by Envelope-free Chloroplasts
High rates of CO2-dependent oxygen evolution have now been observed in a reconstituted system containing ATP, ferredoxin, NADP (nicotinamide adenine dinucleotide phosphate), R5P (ribose-5-phosphate), CE (soluble components released from osmotically shocked chloroplast) and envelope-free chloroplasts.
