Question:
Choose the incorrect statement with reference to the cyclic electron transport
Choose the incorrect statement with reference to the cyclic electron transport
Show Hint
Cyclic photophosphorylation uses PSI and is independent of PSII and wavelength below 680 nm.
Updated On: May 12, 2025
- PSI alone is functional.
- Occurs in stroma lamella.
- Membrane of stroma lamellae lack NADP reductase enzyme.
- Occurs when wavelengths below 680 nm are available for $e^{-}$ excitation.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Cyclic electron transport involves only PSI and occurs in the stroma lamellae where NADP reductase is absent. It operates efficiently under high light intensity or when ATP demand is high. It does not depend on wavelength below 680 nm; instead, it involves PSI that absorbs light at 700 nm.
