Light dependent reaction is the first stage of
photosynthesis, this reaction occurs on the thylakoid membrane, the inner part
of chloroplast. On this stage, light energy is transform to a chemical
energy called ATP (adenosine triphosphate and a reducing power called NADPH (nicotinamide adenine
dinucleotide phosphate). ATP and NADPH are the products in the first stage
of photosynthesis.
