What Is Historical Perspective Of Photosynthesis

What Is Historical Perspective Of Photosynthesis - Nearly all animals need to breathe oxygen to survive. The life-sustaining gas they inhale is made by plants, algae and cyanobacteria during photosynthesis. In a new study published Wednesday in ... Photosynthesis is the only significant solar energy storage process on Earth and is the source of all of our food and most of our energy resources An understanding of the origin and evolution of photosynthesis is therefore of substantial interest as it may help to explain inefficiencies in the process and point the way to attempts to improve

Oxygenic photosynthesis begins with light absorption, followed by excitation energy transfer to the reaction centres, primary photochemistry, electron and proton transport, NADPH and ATP synthesis, and then CO 2 fixation (Calvin-Benson cycle, as well as Hatch-Slack cycle). Overwhelming evidence indicates that eukaryotic photosynthesis originated from endosymbiosis of cyanobacterial-like organisms, which ultimately became chloroplasts ( Margulis, 1992 ). So the evolutionary origin of photosynthesis is to be found in the bacterial domain.

What Is Historical Perspective Of PhotosynthesisWe suggest that (i) after the evolution of red-absorbing Chl-like pigments, the first light-driven electron transport chains reduced ferredoxin via a type-1 reaction center (RC) progenitor with electrons from H2S; (ii) photothioautotrophy, first with one RC and then with two, was the bridge between H2-dependent chemolithoautotrophy and water-spl... Plants algae and cyanobacteria are oxygenic photosynthetizers that use light energy to generate organic molecules e g glucose C 6 H 12 O 6 sugars starch from carbon dioxide CO 2 and water H 2 O and release molecular oxygen O 2 into the atmosphere for a background on photosynthesis see Eaton Rye et al 2012 Blankenship 2014

This paper scans the emergence of structural and mechanistic understanding of oxygen evolution over the past 50 years. It reviews speculative concepts and the stepped insight provided by novel experimental and theoretical techniques.
