Photosynthetic bacteria liberate:
Correct answer: C. S
- A. CO2
- B. H2S
- C. S
- D. H
- E. O
Explanation
In sulfur photosynthetic bacteria, the substance that donates hydrogen is hydrogen sulfide (H2S) and not water. Therefore there is no liberation of molecular oxygen, but there is a production of molecular sulfur (S2). (Oxygen and sulfur have same number of valence electrons.)
