What is NADP,NADPH,ATP,ADP and what has it to do with photosyntesis?

ATP - Adenosine triphosphate
ADP - Adenosine diphosphate
NADP - Nicotinamide adenine dinucleotide phosphate.
NADPH - The reduced form of NADP.
In the Light Dependent Processes i.e Light Reactions, the light strikes chlorophyll a in such a way as to excite electrons to a higher energy state. In a series of reactions the energy is converted, along an electron transport process into ATP and NADPH. Water is split in the process, releasing oxygen as a by-product of the reaction. The ATP and NADPH are used to make C-C bonds in the Light Independent Process (Dark Reactions).
Thus in photosynthesis, these 4 molecules are needed to carry out the various energy conversions.
