Answer:
The main purpose of light dependent reactions of photosynthesis is to generate ATP and NADPH.
Explanation:
Photosynthesis consist of two reactions 1 light reaction 2 dark reaction .The light reaction occur in the thylaKoid of Grana to produce Adenosine tri phosphate (ATP) and NADPH
Role of ATP
ATP is an energy rich molecule which undergo hydrolysis to provide energy for Carbon di oxide fixation during dark reaction. The carbon di oxide fixation is very much important to produce glucose.
Role of NADPH
NADPH act as reducing equivalent that carry out the reduction of phosphoglyceric acid formed in the first step of light independent reaction to generate phosphoglyceraldehyde(PGALD). Some PGALD then undergo various enzymatic reaction to form glucose and rest are utilized to regenerate ribulose bis phosphate(RUBP).
