Detailed explanation-1: -In photosynthesis, a light-dependent reaction uses light energy from the sun to split water which has been taken in by the organism. Water, when split, gives oxygen, hydrogen, and electrons. These electrons move through structures in chloroplasts and, by chemiosmosis, make ATP.
Detailed explanation-2: -Explanation: Light dependent reactions convert solar energy to chemical energy (in the form of ATP and NADPH). Sunlight and H2O are the reactant of the light dependent reaction.
Detailed explanation-3: -When water is split, it produces oxygen, hydrogen, and electrons. These electrons move through chloroplast structures and produce ATP via chemiosmosis. The hydrogen is converted to NADPH, which is then utilized in light-independent reactions.
