Photosynthesis

Description

Photosynthesis is the process used by plants and other organisms that converts light (mostly solar) energy into chemical energy which is subsequently released to fuel organisms' activities. It has two phases: the light-dependent phase and the light-independent (dark) phase. In plants, algae, and cynobacteria, light energy is absorbed during the light phase by the pigment called Chlorophyll and used to split water and generate short-term stores of chemical energy - adenosine triphosphate (ATP), and reducing power - nicotinamide adenine dinucleotide phosphate (NADPH), with the net production of O2 gas as a waste product. And during the dark phase this chemical energy and reducing power are used to synthesize organic matter from the atmospheric CO2 in the form of carbohydrates or sugars through the metabolic pathway called Calvin-Benson cycle. The whole process is what is called oxygenic photosynthesis and is responsible for producing and maintaining the oxygen concentration of the Earth’s atmosphere. In bacteria such as the cyanobacteria photosynthesis involves the plasma membrane and the cytoplasm, and in Eukaryotic cells (plants and algae) photosynthesis takes place inside organelles called chloroplasts.

Photosynthesis as part of PhotoBiology in the context of the NextGen-O2k project

In the NextGen-O2k project we are working on developing the PB-Module for the new series of our O2k-Respirometer, the NextGen-O2k. Similar to our current O2k-Smart Fluo-Module, the PB-Module will provide with an external source of light, in the range of the Blue or Red wavelengths, allowing to carry out experiments for evaluating the production/consumption of O2 in the presence of light.
