The light-dependent reactions of photosynthesis take place within the thylakoids. These reactions occur when the pigment chlorophyll, located within the thylakoid membranes, captures energy from the sun (photons) to initiate the breakdown of water molecules. 2. The light-dependent reactions convert light energy into chemical energy.

Sep 21, 2021 · How Light-Dependent Reactions Work. The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem.
Our retinal pigments can only “see” (absorb) wavelengths between 700 nm and 400 nm of light, a spectrum that is therefore called visible light. For the same reasons, plants, pigment molecules absorb only light in the wavelength range of 700 nm to 400 nm; plant physiologists refer to this range for plants as photosynthetically active radiation.
The visible light seen by humans as white light actually exists in a rainbow of colours. Certain objects, such as a prism or a drop of water, disperse white light to reveal these colours to the human eye. The visible light portion of the electromagnetic spectrum is perceived by the human eye as a rainbow of colours, with violet and blue having ...
Jan 30, 2023 · How Light-Dependent Reactions Work. The overall function of light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP. This chemical energy supports the light-independent reactions and fuels the assembly of sugar molecules. The light-dependent reactions are depicted in Figure 8.16.
