Photosystems I and II convert solar energy into the chemical energy that powers life. Both
photosystems use chlorophyll-a photochemistry, absorbing almost the same color of light …

Photosystems I and II convert solar energy into the chemical energy that powers life.
Chlorophyll a photochemistry, using red light (680 to 700 nm), is near universal and is …

Plants and cyanobacteria use the chlorophylls embedded in their photosystems to absorb
photons and perform charge separation, the first step of converting solar energy to chemical …

A limiting factor for photosynthetic organisms is their light-harvesting efficiency, that is the
efficiency of their conversion of light energy to chemical energy. Small modifications or …

Photosystem I (PSI) converts photons into electrons with a nearly 100% quantum efficiency.
Its minimal energy requirement for photochemistry corresponds to a 700-nm photon …

The photophysical and biochemical properties of chlorophyll (Chl) molecules in
photosynthetic complexes are tuned by the specific molecular environment. This principle …

In the future conversion of solar energy into biofuel and bio‐commodity products, to fight
climate change, cyanobacteria may play a crucial role. Yet, the match between the spectrum …

Chlorophyll d and chlorophyll f are red-shifted chlorophylls, because their Qy absorption
bands are significantly red-shifted compared with chlorophyll a. The red-shifted chlorophylls …

The discovery of cyanobacteria capable of harvesting farred light (near-infrared,
wavelengths> 700 nm) has changed the paradigm that oxygenic photosynthesis is only …

Cyanobacteria carry out photosynthetic light-energy conversion using phycobiliproteins for
light harvesting and the chlorophyll-rich photosystems for photochemistry. While most …
