Which of the following statements is incorrect?

Concept:

Photophosphorylation

• ATP molecules are synthesized by cells (in mitochondria and chloroplast).
• This process of ATP synthesis is called phosphorylation.
• The synthesis of ATP molecules from ADP and inorganic phosphate in the presence of light is called photophosphorylation.

Explanation:

Non-cyclic photophosphorylation

• ​When the two photosystems work in series, PS II followed by PS I, the process is called non-cyclic photophosphorylation.
• Here, photosystems, PS I, and PS II are connected in series by an electron transport chain.
• In this type of process, electrons follow in a non-cyclic manner.
• In PS I, the electrons are transferred to the acceptor molecule, and in presence of an enzyme Ferredoxin- NADP+ reductase, the NADP molecules are reduced to NADPH + H⁺.
• NADP⁺ + 2H⁺ + 2e^- give rise to NADPH + H⁺ .
• In non-cyclic photophosphorylation, in addition to NADPH molecules, ATP molecules are also produced. 

​Cyclic photophosphorylation

• ​When only PS I is present the electrons follow in a cyclic manner. 
• The phosphorylation that occurs due to the cyclic flow of electrons in PS I is called cyclic photophosphorylation.
• In this process, only ATP molecules are formed.

​​​Location for phosphorylation

• Cyclic photophosphorylation occurs in the stroma lamellae.
• Stroma lamellae have only PS I.
• Non-cyclic photophosphorylation occurs in the membrane of grana.
• The grana lamellae have both PS I and PS II.

So, the correct answer is option 1.​
