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.
