Question

About Light reaction ?.​

Answer 1

Light Reaction.----------

It occurs in the Grana where photon are absorbed so as to excite electrons of chlorophyll to a higher energy level. These activated electrons are harnessed to form ATP from ADP and reduce NADP to NADPH. Water is also splitted during this and oxygen is released.

Answer 2

$\textbf{<strong>LIGHT</strong><strong> </strong>REACTION}$

The main purpose of the light reaction is to generate organic energy molecules such as ATP and NADPH which are needed for the subsequent dark reaction. chlorophyll absorbs the red and blue segment of the white light and photosynthesis occur most efficiently, at the these wave lengths
