H2A + CO2 --------> 2A + CH2O + H2O
imagine that H2O is H2S in purple and green sulphur bacteria find the in product
Answers
Explanation:
The green sulfur bacteria (Chlorobiaceae) are a family of obligately anaerobic photoautotrophic bacteria. Together with the non-photosynthetic Ignavibacteriaceae, they form the phylum Chlorobi.[1]

Green sulfur bacteria are nonmotile (except Chloroherpeton thalassium, which may glide) and capable of anoxygenic photosynthesis.[1][2] In contrast to plants, green sulfur bacteria mainly use sulfide ions as electron donors.[3] They are autotrophs that utilize the reverse tricarboxylic acid cycle to fix carbon dioxide.[4] Green sulfur bacteria have been found in depths of up to 145m in the Black Sea, with low light availability.[5]
Characteristics of green-Sulfur bacteria:
Major photosynthetic pigment: Bacteriochlorophylls a plus c, d or e
Location of photosynthetic pigment: Chlorosomes and plasma membranes
Photosynthetic electron donor: H2, H2S, S
Sulfur deposition: Outside of the cell
Metbolic type: Photolithoautotrophs[6]
Answer:
- Similar to how plants do it, some bacteria also carry out bacterial photosynthesis.
- In the presence of sunlight, they emit oxygen, absorb carbon dioxide, and have light-harvesting pigments.
- Sulfur bacteria in purple and green colors are used as an example.
- H2S serves as this bacteria's hydrogen donor. In contrast to plant photosynthesis, where oxygen is emitted, elemental sulphur is not.
- With the exception of Chloroherpeton thalassium, which can glide, green sulphur bacteria are not mobile and can do anoxygenic photosynthesis.
- They exist in anaerobic aquatic habitats. Green sulphur bacteria, as opposed to plants, primarily employ sulphide ions as electron donors.
- They are autotrophs that accomplish carbon fixation through the reverse tricarboxylic acid cycle.
