During light reaction in photosynthesis the following are formed.

Options

A. ATP and sugar
B. hydrogen, `O_(2)` and sugar
C. ATP, hydrogen donor and `O_(2)`
D. ATP, hydrogen and `O_(2)` donor

Answer

C

Explanation

Light reactions occur inside thylakoids. It is dependent upon light. It involves photolysis of water (breaking of water into `H_(2)` and `O_(2)`) and production of assimilatory power (NADPH and ATP). Electron released ruring photolysis of water are picked up by `P_(680)` photocenre of photosystem II. From here electrons passes over series of carrier which include PQgt Cytochrome b-f complex and PCgt while passing over cytochrome complex, the electron losses sufficient energy for creation of proton gradient and ATP from ADP and inorganic of photosystem i, which pushes out electron after absorbing light energy . Electron passes over carriers FeS, ferredoxin and NADP-reductase which gives electron to `NADP^(+)` for combining with `H^(+)` to produce NADPH.
`NADP^(+)+2e^(-)+H^(+)underset("NADP reductase")rarrNADPH`
