Photosynthesis is the process used by plants, algae and somebacteriato turn sunlight into energy. The process chemically converts carbon dioxide (CO2) and water into food (sugars) andoxygen. The chemical reaction often relies on a pigment called chlorophyll, which gives plants their green color....

photosynthetic reaction centerfor the generation of reducing power and chemical energy (Campbell, 1996). In addition to changing the pigment composition, cyanobacteria are also known to alter their morphology in a way that can maximally harvest the available light energy and therefore, increase their ...
Water oxidation into O2was conducted using restacked KCa2Nb3O10nanosheet andIO3−as a reversible electron accepter. The energy change of the total reaction is positive, so-called artificial photosynthesis-type reaction. As shown inFig. 6, layered KCa2Nb3O10exhibited no activity. Interestingly, ...
Photosynthesis originated once during the early Archaean due to the emergence of photochemical reaction centres, the biological nanomachines that convert the energy of light into chemical energy. The evolution of the photosynthetic machinery is consistent with a single origin of photosynthesis followed by...

This type of photosynthesis could have produced banded iron formations similar to those produced by oxygenic photosynthesis. Microfossils, stromatolites, and chemical biomarkers in Australia and South Africa show that cyanobacteria containing chlorophyll a and carrying out oxygenic photosynthesis appeared by ...

This stage is responsible for the conversion of sunlight into chemical energy in the form of ATP and NADPH. The light-independent reaction, also known as the Calvin Cycle, takes place in the stroma of chloroplasts. This stage uses the ATP and NADPH produced during the light-dependent reaction...
