Detailed explanation-1: -The energy from the sun is absorbed by the chlorophyll in the thylakoid membrane of the chloroplasts. The energy is then transferred to ATP and NADPH that is generated by two-electron transport chains. Water is used and oxygen is released during the process.
Detailed explanation-2: -In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.
Detailed explanation-3: -ATP and NADPH produced by the light-dependent reactions of the photosystems are used by the Calvin cycle in the stroma of the chloroplast.
Detailed explanation-4: -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-5: -The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH.
