This pigment absorbs light energy. Light travels as electromagnetic waves. The wavelength — distance between waves — determines energy level. Some of those wavelengths are visible to us as the colors we see. If a molecule, such as chlorophyll, has the right shape, it can absorb the energy from some wavelengths of light.

6 FAQs about [What happens to the solar light energy in photosynthesis]
What is the function of light-dependent reactions in photosynthesis?
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. Protein complexes and pigment molecules work together to produce NADPH and ATP.
How does light energy enter the process of photosynthesis?
Light energy enters the process of photosynthesis when pigments absorb the light. 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.
What happens during a photosynthesis cycle?
The cycle is completed when the light reactions convert these molecules back into ATP and NADPH. There are two types of chlorophyll, a green pigment that captures light for photosynthesis, Chlorophyll a and Chlorophyll b. Figure 25.4: Chlorophyll A & B Absorption Spectrum.
What happens to electrons after a photosynthesis?
The electrons replace those originally lost from chlorophyll. Hydrogen ions and the high-energy electrons from chlorophyll will carry on the energy transformation drama after the light reactions are over. The oxygen atoms, however, form oxygen gas, which is a waste product of photosynthesis.
How do photosynthetic cells capture solar energy?
In plants, some sugar molecules are stored as sucrose or starch. Photosynthetic cells contain chlorophyll and other light-sensitive pigments that capture solar energy. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as glucose.
How do light-dependent reactions begin in photosystem II?
The light-dependent reactions begin in photosystem II. In PSII, energy from sunlight is used to split water, which releases two electrons, two hydrogen atoms, and one oxygen atom. When a chlorophyll a molecule within the reaction center of PSII absorbs a photon, the electron in this molecule attains a higher energy level.
