Dear Student Please find below the solution to the asked query 27 a S No CYCLIC PHOTOPHOSPHORYLATION NON-CYCLIC PHOTOPHOSPHORYLATION 1 Photo system I carry out the reaction Photo system I and II carry out the reaction 2 Active reaction center is P700 Active reaction center is P680 3 Movement of electrons is cyclic Movement of electron is non-cyclic 4 There is no photolysis of water during the reaction There is a photolysis of water during the reaction 5 No production of oxygen Oxygen is produced as a byproduct 6 Electrons from PS I comes back to PS I Electrons from PS I are accepted by the NADPH 7 During this reaction only ATP is produced Both ATP and NADP are produced during the reaction 8 It mainly occurs in bacteria It mainly occurs in plants Non-Cyclic Photo-Phosphorylation

Cyclic Photo-Phosphorylation

27 b Law of Limiting factor was given by Blackman This law governs the rate of photosynthesis According to this law, the process of photosynthesis is controlled by many factors but the rate of photosynthesis will depend on the factor which is present in limited quantity For example, photosynthesis depends on carbon dioxide concentration, light intensity, water, presence of chlorophyll If all factors are present but light intensity is low then the light will become the limiting factor and rate of photosynthesis will depend only on light, the limiting factor Hope this information will clear your doubts about the topic If you have any more doubts just ask here on the forum and our experts will try to help you out as soon as possible Regards

S.No	CYCLIC PHOTOPHOSPHORYLATION	NON-CYCLIC PHOTOPHOSPHORYLATION
1.	Photo system I carry out the reaction.	Photo system I and II carry out the reaction.
2.	Active reaction center is P700.	Active reaction center is P680.
3.	Movement of electrons is cyclic.	Movement of electron is non-cyclic.
4.	There is no photolysis of water during the reaction.	There is a photolysis of water during the reaction.
5.	No production of oxygen.	Oxygen is produced as a byproduct.
6.	Electrons from PS I comes back to PS I.	Electrons from PS I are accepted by the NADPH.
7.	During this reaction only ATP is produced.	Both ATP and NADP are produced during the reaction.
8.	It mainly occurs in bacteria.	It mainly occurs in plants.
