The splitting up of water molecule in the light dependent part of photosynthesis is done with the help of chemical energy or not?

Expert Answer:

Light energy is needed to split water molecule during photosynthesis.

In the Light Dependent Processes (Light Reactions) 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).
