Q995
Condition favouring cyclic photophosphorylation is
A.
Anaerobic environment
B.
Aerobic and low light intensity
AnswerC.
Aerobic and optimum light
D.
Anaerobic and low light intensity
Answer: Option B
Solution
Answer: Option B
Solution:
Condition favouring cyclic photophosphorylation is Aerobic and low light intensity.Cyclic photophosphorylation occurs on the stroma lamella, or fret channels. In cyclic photophosphorylation, the high-energy electron released from P700, a pigment in a complex called photosystem I, flows in a cyclic pathway.
It is favoured in anaerobic conditions and conditions of high irradiance and CO2 compensation points.
