Photosynthesis, the natural process of converting sunlight energy into chemical energy and generating molecular oxygen, is a ...

An international team of scientists has solved a key piece of Earth’s evolutionary puzzle by uncovering the structure of a light-harvesting nanodevice in one of the planet’s most ancient ...

Cyanobacteria began contributing oxygen to Earth’s mostly noxious atmosphere more than 2 billion years ago. The photosystem II protein complex now shared by various lineages of cyanobacteria, algae ...

The authors note that, due to a production error, a footnote denoting equal contribution of one author was omitted. The following footnote should have been included for authors Fei-Yu He, Long-Sheng ...

Dieses besonders langwellig absorbierende Chlorophyllmolekül (Photosystem I: Chlorophyll P 700, Photosystem II: Chlorophyll P 680) wird dadurch angeregt, d. h. in den ersten Singulett-Anregungszustand ...

Sie sind in Form einer Elektronenkette angeordnet, die aus Protein- und Lipidredoxsystemen besteht und nur ein einziges Photosystem, das bakterielle Photosystem (BPS, bacterial pigment system), ...

The water molecules are split by a large enzyme—a protein structure that acts as a catalyst, speeding up biochemical reactions—called Photosystem II. Its name is a historical accident ...

One such mystery is how Photosystem II, a protein complex in plants, algae and cyanobacteria, harvests energy from sunlight and uses it to split water, producing the oxygen we breathe. Now ...

Dissection of the electron transport pathway in photosystem II (PS II) under water deficit and heat stress can shed light on the various attributes of the photosynthetic performance of a plant. We ...

Photosystem I in plants shows a hitherto unknown face / Molecular examination with maximum precision Photosynthesis is the most important basis of life on Earth. In it, plants and single-cell algae ...

The first step of this process involves an enzyme called photosystem II, which uses light energy to extract electrons from water to help capture the carbon dioxide. If the photosystem absorbs too much ...
