Which of the following conditions are favourable for cyclic photophosphorylation?
Options
(a) anaerobic condition
(b) aerobic and low light intensity
(c) aerobic and optimum light
(d) anaerobic and low light intensity
Correct Answer:
anaerobic and low light intensity
Explanation:
Cyclic photophosphorylation is performed by photosystem I(P₇₀₀) it is a process of photophosphorylation in which an electron expelled by the excited photocentre is returned to it after passing through a series of electron carriers. Electrons used in the cyclic photophosphorylation do not come from water, i.e. water is not oxidised and oxygen is not evolved in the process. It occurs under conditions of low light intensity wavelength longer than 680 nm, and when CO₂ fixation is inhibitied.
