1.	Question : The purple sulphur bacteria use hydrogen sulphide and release sulphur but not oxygen. Which of the following agrees with above observation
Answer» The `H_(2)` that resuces `CO_(2)` comes from `H_(2)S` that liberates sulphur Photosynthesis does not require chlorophyll Photosynthesis consist of a light and a dark reaction The `H_(2)` which reduces `CO_(2)` in photosynthesis comes from `H_(2)O` that RELEASES `O_(2)` SOLUTION :`6CO_(2)+12H_(2)S OVERSET("Light")(rarr) C_(6)H_(12)O_(6)+12S+6H_(2)O+` energy. Here `H_(2)S` is utilized as a SOURCE of hydrogen, which reduces `CO_(2)` into glucose. Oxygen is not liberated in bacterial photosynthesis.
