Detailed explanation-1: -Light reaction is the first stage of photosynthesis process in which solar energy is converted into chemical energy in the form of ATP and NADPH. The protein complexes and the pigment molecules help in the production of NADPH and ATP.
Detailed explanation-2: -The first step in photosynthesis is the photo excitation of chlorophyll by a photon of light.
Detailed explanation-3: -The first stage of photosynthesis is called the light reactions. During this stage, light is absorbed and transformed to chemical energy in the bonds of NADPH and ATP.
Detailed explanation-4: -The light reaction of photosynthesis produces ATP and NADPH which in turn serve as the energy source to drive the second phase of photosynthesis (dark reactions) during which carbohydrate synthesis takes place.
Detailed explanation-5: -Steps of the Light Reactions The light reactions occur in several steps, all of which take place in the thylakoid membrane. 0 Step 1: Units of sunlight, called photons, strike a molecule of chlorophyll in photosystem II of the thylakoid membrane.
