Sep 21, 2021 · 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.

In plants, pigment molecules absorb only visible light for photosynthesis. The visible light seen by humans as white light actually exists in a rainbow of colors. Certain objects, such as a prism or a drop of water, disperse white light to reveal these colors to the human eye.

The light reaction is also known as photolysis reaction and takes place in the presence of light. It usually takes place in the grana of chloroplasts. The photosystems have pigment molecules. In the plants, chlorophyll is one of the primary pigments which actively takes part in the process of light reactions like photosynthesis. The accessory pigme...
Light reaction is the first stage of photosynthesis processin 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. The process of light reaction is given below- 1. In light reactions, energy from the sunlight is absorbed by the pig...
The light reaction traps the energy from the sun and converts it into chemical energy that is stored in NADPH and ATP.Oxygen is released as the waste product.- 13 min
The overall function of light-dependent reactions, the first stage of photosynthesis, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent reactions and fuel the assembly of sugar molecules.
The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem. Photosystems exist in the membranes of thylakoids. A pigment molecule in the photosystem absorbs one photon, a quantity or “packet” of light energy, at a time.
