Protein complexes in photosynthesis

Most chapters are dedicated to one protein, while a few also summarize Protein complex b 6 f. Credit: University of Sheffield. The sun’s light fires up a plant’s sugar-making factories as the first step of photosynthesis, energizing electrons in the pigment The harvesting of photons is the first step in photosynthesis, the biological process that transforms solar energy into chemical energy. The photosynthetic membranes of algae and plants are packed However, photosynthesis is a complex microscopic process and some of its aspects are still not well understood. For example, Photosystem I (PSI) is a complicated protein system involved in Photosystem II (or water-plastoquinone oxidoreductase) is the first protein complex in the light-dependent reactions of oxygenic photosynthesis.It is located in the thylakoid membrane of plants, algae, and cyanobacteria.

At the heart of the photosystem is the reaction centre, an enzyme that uses light to reduce molecules. This reaction centre is surrounded by light-harvesting complexes, protein assemblies that enhance the absorption of light.

Other proteins include enzymes and protein-containing coenzymes.

The photosynthetic unit includes the reaction centers (RC 1 and RC 2) and the light-harvesting complexes which contribute to evolution of one O 2 molecule. The light-harvesting complexes, that greatly expand the absorptance capacity of the reactions, have evolved along three principal lines.

Photosynthesis - Photosynthesis - Proteins: Many of the lamellar proteins are components of the chlorophyll–protein complexes described above. Other proteins include enzymes and protein-containing coenzymes. Enzymes are required as organic catalysts for specific reactions within the lamellae. Protein coenzymes, also called cofactors, include important electron carrier molecules called cytochromes, which are iron-containing pigments with the pigment portions attached to protein molecules.
