2. Light-dependent reactions - Wikipedia

   en.wikipedia.org/wiki/Light-dependent_reactions

   In oxygenic photosynthesis, the first electron donor is water, creating oxygen (O 2) as a by-product. In anoxygenic photosynthesis, various electron donors are used. Cytochrome b 6 f and ATP synthase work together to produce ATP (photophosphorylation) in two distinct ways.

3. Photosynthetic efficiency - Wikipedia

   en.wikipedia.org/wiki/Photosynthetic_efficiency

   Photosynthesis is the only process that allows the conversion of atmospheric carbon (CO2) to organic (solid) carbon, and this process plays an essential role in climate models. This lead researchers to study the sun-induced chlorophyll fluorescence (i.e., chlorophyll fluorescence that uses the Sun as illumination source; the glow of a plant) as ...

4. Photosynthetically active radiation - Wikipedia

   en.wikipedia.org/wiki/Photosynthetically_active...

   Radiation reaching a plant contains entropy as well as energy, and combining those two concepts the exergy can be determined. This sort of analysis is known as exergy analysis or second law analysis, and the exergy represents a measure of the useful work, i.e., the useful part of radiation which can be transformed into other forms of energy.

5. Light-harvesting complex - Wikipedia

   en.wikipedia.org/wiki/Light-harvesting_complex

   Photosynthesis is a process where light is absorbed or harvested by pigment protein complexes which are able to turn sunlight into energy. [5] Absorption of a photon by a molecule takes place when pigment protein complexes harvest sunlight leading to electronic excitation delivered to the reaction centre where the process of charge separation can take place.

6. Photophosphorylation - Wikipedia

   en.wikipedia.org/wiki/Photophosphorylation

   So, in the presence of light, synthesis of food is called 'photosynthesis'. Noncyclic photophosphorylation through light-dependent reactions of photosynthesis at the thylakoid membrane. In the process of photosynthesis, the phosphorylation of ADP to form ATP using the energy of sunlight is called photophosphorylation. Cyclic ...

7. Quantum biology - Wikipedia

   en.wikipedia.org/wiki/Quantum_biology

   Photosynthesis refers to the biological process that photosynthetic cells use to synthesize organic compounds from inorganic starting materials using sunlight. [58] What has been primarily implicated as exhibiting non-trivial quantum behaviors is the light reaction stage of photosynthesis.

   Candy canes are a peppermint treat long associated with Christmas. Learn their history, including why they were first made with red and white stripes.

9. Photosynthesis - Wikipedia

   en.wikipedia.org/wiki/Photosynthesis

   To use this stored chemical energy, an organism's cells metabolize the organic compounds through cellular respiration. Photosynthesis plays a critical role in producing and maintaining the oxygen content of the Earth's atmosphere, and it supplies most of the biological energy necessary for complex life on Earth. [2]
