Question

Which of the following can utilize light energy for the synthesis of ATP?

• A. Slime molds
• B. Thermoacidophiles
  
• C. Halophiles
• D. All of the above

Answer 1

Answer: (C)

Halophiles

Halophiles are the organisms which can survive in the regions or zones with higher salt concentrations. The halophiles are the primitive bacteria which belong to the group of archaebacteria. These bacteria possess a protein called as bacteriorhodopsin which can capture light. The proton gradient is created and the ATP is synthesized with the use of the sunlight.

Thus, the correct answer is option C.
