Question

Where does the energy come from to make ATP in the light reactions?

Answer 1

Answer:

The correct answer is c from the motion of hydrogen ions.

Explanation:

Photosynthesis consist of 2 reactions among them one is light reaction and the other is dark reaction.

 Light reaction deals with the formation of ATP and NADPH,The ATP is formed by the flow of electrons through various electron carriers which is simultaneous to the transport of protons along their concentration gradient resulting in the formation of proton motive force(PMF).

  The generated PMF leads to form ATP.
