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, … With its extensive use of color, it surveys the most important proteins involved in photosynthesis, discussing the structural information we have at our disposal.

LIGHT HARVESTING COMPLEXES IN HIGHER PLANTS

The light absorption processes associated with photosynthesis take place in large protein complexes known as photosystems. The one known as Photosystem II contains the same kind of chlorophyll a as Photosystem I but in a different protein environment with an absorption peak at 680 nm.

Protein complexes in photosynthesis

An international team of researchers has solved the structure and elucidated the function of photosynthetic complex I. This membrane protein complex plays a major role in dynamically rewiring photosynthesis. As the first phase of photosynthesis is light dependent, it is referred to as light reaction; however this is also called. Hill’s reaction for, it was first demonstrated by Robert Hill. Basic principles involved in photosynthesis is capturing of solar electromagnetic radiations at a particular wave length by pigment/protein complexes.

Most chapters are dedicated to one protein, while a few also summarize general associated concepts. Photosystems are functional and structural units of protein complexes involved in photosynthesis that together carry out the primary photochemistry of photosynthesis: the absorption of light and the transfer of energy and electrons. Photosystems are found in the thylakoid membranes of plants, algae and cyanobacteria which are located inside the chloroplasts of plants and algae, and in the cytoplasmic membrane of photosynthetic bacteria. There are two kinds of photosystems: I and II. The photosynthetic unit includes the reaction centers (RC 1 and RC 2) and the light-harvesting complexes which contribute to evolution of one O2 molecule. The light-harvesting complexes, that greatly expand the absorptance capacity of the reactions, have evolved along three principal lines.
