Science news articles about 'chlorophyll molecules'

An international team of scientists has determined the structure of the chlorophyll molecules in green bacteria that are responsible for harvesting light energy. The team's results one day could be ...

... organic pigment that occurs naturally in plants and other photosynthetic organisms. Porphyrin is similar to a chlorophyll molecule and exists in green leaves and red blood cells. Fullerene is composed ...

... undergoing a conformational change which alters the reduction potential of excitonically-coupled chlorophyll molecules. This then promotes the charge-transfer with zeaxanthin that produces radical ...

... the genetic instructions in the algae genome responsible for deploying approximately 600 chlorophyll molecules in the cell's light-gathering antennae. The Berkeley researchers figure that the algae ...

... less green." That is, they hope to modify the tiny organisms so as to minimize the number of chlorophyll molecules needed to harvest light without compromising the photosynthesis process in the cells.

... II generates oxygen by splitting water molecules. Because oxygen inhibits nitrogen fixation, ... II is large complex of multiple proteins and chlorophyll molecules, but the team was unable to find any ...

... identified the genetic instructions in the algae genome responsible for deploying approximately 600 chlorophyll molecules in the cell's light-gathering antennae. They believe that the algae can get ...

... in chlorosomes of green bacteria. Chlorosomes are the light harvesting antennae of these bacteria. They are elongated small pockets which can accommodate up to 250,000 chlorophyll molecules...

... in highly unfavourable light conditions, such as deep in the sea. These chlorosomes are made up of chlorophyll molecules. The art is to imitate these systems very precisely. German colleagues ...
