Question

Choose the correct answer from the alternatives given.
Production of NADPH in a chloroplast takes place during

• A. cyclic photophosphorylation
• B. non-cyclic photophosphorylation
• C. series photophosphorylation
• D. substrate level photophosphorylation

Answer 1

The correct option is B non-cyclic photophosphorylation

During non-cyclic photophosphorylation, the electrons released by P700 are carried by primary acceptor and are finally passed on to NADP. Here, the electrons combine with the protons H+ which is produced by splitting up of the water molecule and reduces NADP to NADPH${}_2$.

Thus, the correct answer is 'Non-cyclic photophosphorylation.'
