Sulfide is used as a reducing agent during photosynthesis in green and sulfur bacteria.
Energy in the form of sunlight
The light dependent reactions take place when the light excites a reaction center, which donates an electron to another molecule and starts the electron transport chain to produce ATP and NADPH.
Once NADPH has been produced, the Calvin cycle[1] proceeds as in oxygenic photosynthesis, turning CO2 into glucose.
Anoxygenic photosynthesis is a special form of photosynthesis used by some bacteria and archaea, which differs from the better known oxygenic photosynthesis in plants in the reductant used (e.g. hydrogen sulfide instead of water) and the byproduct generated (e.g. elemental sulfur instead of molecular oxygen).
