Which of the following statements is more accurate?

I. Photosystem I: Breaking down of water molecules :: Photosystem II: creating NADPH from NADP

II. Electron Transport Chain allows electrons to gain more energy while travelling from one photosystem to another, thus, sustaining its energy for ATP production when it reaches the end of the photosystem.

III. The products of the light reaction of photosynthesis are sorted only as ATP and NADPH.

• I Only

• II Only

• I and II

• II and III

• None of The Above
