A) They have both cyclic and non-cyclic photo phosphorylation
B) They absorb light > 900 nm of wavelength
C) They release \[{{\text{O}}_{\text{2}}}\] during photosynthesis
D) They use\[{{\text{H}}_{\text{2}}}\text{O}\] during photosynthesis
Correct Answer: B
Solution :
Photosynthetic bacteria contain bacterial chlorophyll as a light trapping pigment molecule that absorbs light between 800 to 925 nm, depending on the species of bacteria. Bacterial photosynthesis occurs without evolution of \[{{\text{O}}_{2}}\] (it is anoxygenic process) as water \[({{H}_{2}}O)\] is not used as hydrogen donor. Instead of\[{{\text{H}}_{\text{2}}}\text{,}\,\,{{\text{H}}_{\text{2}}}\text{S}\] and other similar compounds are employed as the electron donor. Bacteria have only one pigment system similar to that of \[\text{PS}-\text{I}\] thus, only cyclic photophosphorylation occurs in hotosynthetic bacteria.You need to login to perform this action.
