Question

Which one of the following concerns photophosphorylation?

ADP + AMP ATP

(b) ADP + Inorganic PQ,

(c) ADP + Inorganic P04 ATP

(d) AMP + Inorganic PQ, ATP

Answer 1

The reaction in which addition of inorganic phosphate group to a compound of adenosine diphosphate (ADP) during the light reaction and formation of adenosine tri phosphate (ATP) is called as photophosphorylation.

Photophosphorylation involved two pigments for excitation namely PS1 (photosystem 1) and PS2 (photosystem 2). PS1 excited at 700 nm and PS2 at 680 nm. The reaction is written like as follows:

ADP + Inorganic PO4 ATP the catalyst for this reaction is light.

Hence option (c) is correct.
