Write the steps involved in light dependent reaction.
Answers
Answer:
These reactions occur within specialised membrane discs within the chloroplast called thylakoids and involve three steps: Excitation of photosystems by light energy. Production of ATP via an electron transport chain. Reduction of NADP+ and the photolysis of water
Answer:
light dependent reactions are also called as photochemical phase which takes place in grana of chloroplast .
Explanation:
several steps occur in the light dependent reactions.
step 1: the chlorophyll on exposure to light energy becomes activated by absorbing photons .
step 2: The enegry is used in splitting the water molecules into components ions named hydrogen (H+) , hydroxyl ion (OH-), .This reaction is know as photolysis.
step 3: OH- ions through a series of steps produce water (H2O)and O2 .
The end products of light reaction are ATP,NADPH, and O2.
