Class 11 NEET Biology Photosynthesis in Higher Plants

• Cyclic photophosphorylation involves only PS I.
Both PS I and PS II are involved in non-cyclic photophosphorylation where both ATP and NADPH + H‌+ are synthesized.
• Both PS I and PS II are found on grana lamellae whereas stroma lamellae have PS I only and lack NADP reductase.
