Question

What outputs of the light dependant reaction does not go into the light independant reaction. how are they produced and where do they go after being produced?

Answer 1

light reactions occur in the thylakoid of the chloroplast, water is split to produce oxygen, ATP is produced by the ATP synthase, also NADPH is produced.

so products of light-dependent reactions are ATP, NADPH and oxygen.

photons excite the electrons from the PSII ( Photosystem II) and electrons move through the electron transport chain, and finally, NADP+ reductase reduces NADP+ to NADPH ( pathway of electrons is PSII plastoquinonecytochrome b6f plastocyaninPSIferredoxinferredoxin-NADP reductase). during electron transport H+ from the stroma is pumped to the thylakoid lumen, creating an H+ gradient across the thylakoid membrane, ATP synthase uses the energy of H+ gradient to make ATP from ADP and Pi.

oxygen is released through stomata or used in cellular respiration.

ATP and NADPH are used in the Calvin cycle to synthesize sugar.
