Detailed explanation-1: -The given statement is true. The light-dependent reaction of photosynthesis consists of four systems.
Detailed explanation-2: -Light-dependent reactions happen in the thylakoid membrane of the chloroplasts and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions. The chlorophyll in the plants absorb sunlight and transfers to the photosystem which are responsible for photosynthesis.
Detailed explanation-3: -The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.
Detailed explanation-4: -Which is true of light dependent reactions? 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-5: -Answer and Explanation: The correct answer is option C. The light-dependent reaction of photosynthesis does not use ATP and NADPH in any of its processes.
