Detailed explanation-1: -In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the hydrogen carrier NADPH and the energy-storage molecule ATP. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
Detailed explanation-2: -The first step of photosynthesis is Light-dependent. The three main components of this step are water, carbon dioxide, and sunlight. Carbon Dioxide and water enter the leaf, and the sunlight is absorbed to produce energy in the whole process.
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: -During photosynthesis, the first reaction (called the light reactions of photosynthesis) will produce ATP (through oxidative phosphorylation), and will also produce NADPH, an electron carrier that will carry electrons into the second set of reactions of photosynthesis called the Calvin cycle.
Detailed explanation-5: -1st step is oxidation of chlorophyll by the light energy to release energy rich electrons for synthesizing chemical energy.
