Description
Photosynthesis is the process that converts light energy into chemical energy which is subsequently transformed to the physiological energy demand. Photosynthesis has a light-dependent and light-independent (dark) phase. In plants, algae, and cynobacteria, light energy is absorbed during the light phase by the pigment chlorophyll and used to split water and generate adenosine triphosphate (ATP) and reducing power - nicotinamide adenine dinucleotide phosphate (NADPH), with the net production of O2 as a waste product. During the dark phase ATP and NADPH are used to synthesize carbohydrates from CO2 through the metabolic pathway called Calvin-Benson cycle. Oxygenic photosynthesis is responsible for producing and maintaining the oxygen concentration of the Earthβs atmosphere. In bacteria such as cyanobacteria, photosynthesis involves the plasma membrane and the cytoplasm. In eukaryotic cells (plants and algae), photosynthesis takes place in the chloroplasts.

PhotoBiology in the context of the NextGen-O2k project
- In the NextGen-O2k project we developed the PhotoBiology Module (PB-Module). Similar to the O2k-Fluo Smart-Module, the PB-Module contains a light source (blue, red, or white) allowing high-resolution monitoring of production and consumption of O2.
