ATP is created during the light reactions of photosynthesis in a manner that is similar to cellular respiration. How is this accomplished?

• by a proton concentration gradient and ATP synthersis

• by the citric acid cycle and NAD+ reduction

• by splitting of a water molecule and movement of electrons through ATP synthase

• by creation of water molecule by joining protons and electrons

• by the energy derived from photosystems 1 and 2
