Light reaction is a process to produce

Light reaction is a process to produce ATP and reduction NADPH2. This reaction requires water molecules. The process begins with the capture of photons by the antenna pigments.Chlorophyll pigments absorb more visible light to blue (400-450 nanometers) and red (650-700 nanometers) than green (500-600 nanometers). The green light will be reflected and captured by our eyes causing a sensation that the leaves are green. Photosynthesis will produce more energy at a particular wave length of light. This is because the shorter wavelengths greater energy savings.
In the leaves, the light is absorbed by chlorophyll molecules to be collected at the reaction centers. Plants have two types of pigments that function as active as the reaction center or photosystem II and photosystem I. Photosystem Photosystem II consists of chlorophyll molecules that absorb light with a wavelength of 680 nanometers, 700 nanometers whereas photosystem I. The two photosystems this will work simultaneously in photosynthesis, such as the two batteries in a flashlight that works mutually reinforcing.
Photosynthesis begins when light ionizes the chlorophyll molecules in Photosystem II, releasing electrons are transferred along the electron transport chain. The energy of the electron is used for photophosphorylation that produce ATP, the energy exchange in the cell unit. Photosystem II reaction causes a deficit or lack of electrons that must be replaced immediately. In plants and algae, the electron deficiency is filled by electrons from the ionization of water ionization occurs simultaneously with chlorophyll. The result is an electron ionization of water and oxygen.
