what is the role of carbon dioxide, NADP, water, oxygen and ATP in photosynthesis?

CO2 - provides carbon for the Calvin cycle (Dark reaction) which will be reduced to organic carbon which the cell can use.

NADP - Is the last electron acceptor in the non-cyclic electron transport chain of the light reaction. When it accepts the electron, it is reduced to NADPH which is a powerful reductant that is used in biosynthesis (like the Calvin cycle)

Water - Provides the electrons to start the light reaction.

Oxygen - Waste product formed when the electron are stripped off of water to start the light reaction.

ATP - is made during the light reaction via the buildup of a proton gradient across the thylakoid membrane. The gradient is formed by harvesting the decay of energy from the electron taken from water as it passes through an electron transport chain in the thylakoid membrane. The gradient is then dissipated through ATP synthase in the thylakoid membrane making ATP which is used in the dark reaction.
