Q.
Which out of the following statements is incorrect [2023]

1 Grana lamellae have both PS I and PS II.

2 Cyclic photophosphorylation involves both PS I and PS II.

3 Both ATP and NADPH + $H^{+}$ are synthesised during non-cyclic photophosphorylation.

4 Stroma lamellae lack PS II and NADP reductase.

Ans.
(2)

Cyclic photophosphorylation is a process of light reaction during which an excited electron expelled by the photoreceptor (PS I) is returned to itself, i.e., (PS I) after passing through a series of electron carriers. It occurs under conditions of low light intensity, wavelength longer than 680 nm and when carbon dioxide fixation is inhibited. It is performed by photosystem I only. The cyclic flow hence, results only in the synthesis of ATP, but not of NADPH + $H^{+}$
