- Absorption of Light Light energy enters the process of photosynthesis when pigments absorb the light. In plants, pigment molecules absorb only visible light for photosynthesis.
In this section, we will explore the absorption of light by the light-harvesting complex (LHCII) of the LHC-PSII supercomplex. Before we get into too much detail, let's start with a simplified review of light absorption in the LHCII.

Absorption is a physiological mechanism by which simpler forms of molecules(both macromolecules and micromolecules) are transmitted (absorbed/assimilated) from the intestinal lumen to the circulatory system (blood or lymphatic). This process occurs across the mucosa of the intestine via the epithelial cells’ barrier that constitutes it. Some of the...

Dec 16, 2021 · Light energy initiates the process of photosynthesis when pigments absorb the light. Organic pigments have a narrow range of energy levels that they can absorb. Energy levels lower than those represented by red light are insufficient to raise an orbital electron to an excited, or quantum, state.
Instead, photosynthetic organisms contain light-absorbing molecules called pigments that absorb only specific wavelengths of visible light, while reflecting others. The set of wavelengths absorbed by a pigment is its absorption spectrum .

Light absorption is the process by which molecules, such as pigments in photosynthetic organisms, capture light energy from sunlight. This energy is crucial for driving the light reactions of photosynthesis, where it is transformed into chemical energy in the form of ATP and NADPH.
Sep 20, 2024 · Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
