Over time, the heat energy reaches the sun's surface, where some of it is converted to light by black body radiation that reaches the earth.
Bryant ed. Mitchell's proposal that energy is stored as an electrochemical gradient across a vesicular membrane opened the door for understanding energy transformation by membrane systems.
Smith 1994 Crystal structure of chloroplast cytochrome f reveals a novel cytochrome fold and unexpected heme ligation. Oceanic algae contribute enormous quantities of food and oxygen to global food chains.
Proposal for the domains Archaea, Bacteria and Eucarya. There is evidence that chloroplasts were once free living bacteria that invaded a non-photosynthetic cell long ago. The net effect of the light reactions is to convert radiant energy into redox free energy in the form of NADPH and phosphate group-transfer energy in the form of ATP. Lavergne, J.
Yachandra 1993 Perspectives on the structure of the photosynthetic oxygen evolving manganese complex and its relation to the Kok's cycle. By harnessing energy from the sun, photosynthesis allowed living things to access enormous amounts of energy.
What is the overall purpose of the light reactions in photosynthesis? In the Calvin cycle, which takes place in the stroma, the chemical energy derived from the light-dependent reactions drives both the capture of carbon in carbon dioxide molecules and the subsequent assembly of sugar molecules.
Academic Press, Orlando. Why PS II reaction centers contain redox components that are not involved in the primary enzymatic reactions is a puzzling question.
Anoxygenic photosynthetic bacteria are photoautotrophs synthesize food using sunlight that don't produce oxygen.
Recent work indicates that the D1 and D2 polypeptides also provide ligands for the Mn 4 cluster. Most marine phytoplankton are composed of diatoms and dinoflagellates.
An interesting time line of the history of photosynthesis has been presented by Huzisige and Ke 1993. Govindjee, J.
Fork eds. Moreover, the oxygen humans and other animals breathe is the oxygen released during photosynthesis.
