Differences between noncyclic and cyclic electron transport pathways.

Open in App

Solution

Non-cyclic electron transport pathway Cyclic electron transport pathway
Two photosystems, PSI (P700) and PSII (P680) are involved. Only one photosystem, PSI (P700)is involved.
The electron flow is non-cyclic and the final electron acceptor is NADP. The electron flow is cyclic and the final electron acceptor is P700.
Photolysis (splitting of water) of water occurs. Photolysis of water does not occur.
ATP and NADP are the final products formed. Only ATP is formed.
Oxygen is evolved. Oxygen is not evolved.
Occurs in high light intensity conditions. Occurs in low light intensity.
Occurs in green plants. Occurs mostly in bacteria.
