Conditions required for cyclic photophosphorylation are

  • A
    aerobic condition, low light intensity
  • Correct answer
    B
    aerobic condition, optimum light intensity
  • C
    anaerobic condition, low light intensity
  • D
    anaerobic condition, optimum light intensity

Solution

The conditions required for cyclic photophosphorylation are aerobic condition and optimum light intensity. It is a process of photophosphorylation in which an electron expelled by the excited photocentre is returned. This electron passes through a series of electron carriers. Cyclic photophosphorylation is performed by photosystem-I only.

Hence, the correct answer is option: 'B'.
