Hello,

The cyclic and non cyclic photo phosphorylation are two important features of Light reaction during photosynthesis.

The product of the light reaction are required for Dark reaction.

• In non-cyclic photophosphorylation 1 ATP and 2 NADPH2 molecules are produced. Further each NADPH2 molecule produce 3 ATP molecules, hence you can consider the total number of ATPs  produced are 7.

• In cyclic photophosphorylation 2 ATP molecules are produced per cycle.

i hope you find the answer helpful.

Thank you.

Hi!!!

Hope you are doing well.

Non-Cyclic photophosphorylation produces 1 ATP and 2 NADPH2 molecules. On the other hand, in cyclic photophosphorylation 2 ATP molecules are produced.

Hope you are clear now. Feel free to ask if you have any other queries. All The Best!!!
