The higher plant chloroplast thylakoid membrane system performs the light-dependent reactions of photosynthesis. These provide the ATP and NADPH required for the fixation of CO2 into biomass by the Calvin-Benson cycle and a range of other metabolic reactions in the stroma. Land plants are frequently...
Recognizing the importance of the environment, this chapter provides an overview of different fumigation methods and discusses their relevance. It deals on direct effects of SO 2 , NO x , O 3 , and acid precipitation on photosynthesis, respiration, and stomata, under the influence of climate ...
3.3 Rises in concentrations of carbon dioxide The basic ingredients of HYPERLINK .au/nova/091/091glo.htm \l photosynthesis photosynthesis are carbon dioxide and water. Increased carbon dioxide in the atmosphere causes increased growth rates in many plant species. This is good news for farmers, but...

Light is essential for photosynthesis, but the amounts of light that exceed an organism’s assimilation capacity can result in oxidative stress and even cell death. Plants and microalgae have developed a photoprotective response mechanism, qE, that dissipates excess light energy as thermal energy. ...
In leaves, tocopherols prevent oxidative damage of thylakoid membranes and hence allow efficient photosynthetic electron transport. Consequently, it has been reported that vitamin E can delay leaf senescence55,56and thereby potentially enable longer phases of photosynthesis and grain filling. In this conte...

Given that photorespiration is inextricably linked to the process of photosynthesis by virtue of sharing the common first enzyme Rubisco, the photorespiratory pathway has been less subject to study in isolation than many other metabolic pathways. That said, despite often being described to be linked ...

However, one of the greatest defects of an isolated system in vitro is its instability. Hence an ...
Previous results have emphasized that the production of oxygen bubbles by cells via photosynthesis is directly connected to scum formation19. Similarly, the production of gas bubbles was observed in the strains tested here, in the presence of Mg2+ and Ca2+ ions, but only in the absence of EDTA...
