Vedclass · Answer

(D) The thylakoid membranes are differentiated into two regions: grana lamellae and stroma lamellae.The grana lamellae (or grana stacks) are rich in $PS\, II$ and $LHC$ (Light Harvesting Complex),but they contain very little $ATP$ synthetase.In contrast,the stroma lamellae (stromal thylakoids) are rich in $PS\, I$ and $ATP$ synthetase,but they are poor in $PS\, II$ and $LHC$.Since the Assertion states that stromal thylakoids are rich in both $PS\, I$ and $PS\, II$,the Assertion is incorrect because they are poor in $PS\, II$.The Reason states that stroma membranes are rich in $ATP$ synthetase,which is correct.Therefore,the Assertion is incorrect,but the Reason is correct.

Assertion: The stromal thylakoids are rich in both $PS\, I$ and $PS\, II.$
Reason: The stroma membranes are rich in $ATP$ synthetase.
