Question

Assertion: Cyclic photo phosphyorylation synthesizes ATP.
Reason: ATP synthesize in cyclic phosphyorylation is associated with NADPH formation.

• A. Both reason and assertion are true and the reason is the correct explanation for the assertion.
• B. Both the reason and assertion are true but the reason is not the correct explanation of the assertion.
• C. Assertion is true but the reason is false.
• D. Both the assertion and reason are false

Answer 1

The correct option is C Assertion is true but the reason is false.

In the case of cyclic phosphorylation, the electron, while passing between ferredoxin and plastoquinone and or over the cytochrome complex the electron loses sufficient energy to form ATP from ADP and inorganic phosphate However, is not donated to NADP${}^{+}$.
