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. 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.

5. Photosynthesis - Wikipedia

   en.wikipedia.org/wiki/Photosynthesis

   In plants, algae, and cyanobacteria, photosynthesis releases oxygen. This oxygenic photosynthesis is by far the most common type of photosynthesis used by living organisms. Some shade-loving plants (sciophytes) produce such low levels of oxygen during photosynthesis that they use all of it themselves instead of releasing it to the atmosphere. [12]

6. Photosynthetic reaction centre - Wikipedia

   en.wikipedia.org/wiki/Photosynthetic_reaction_centre

   Photosystem II is present on the thylakoid membranes inside chloroplasts, the site of photosynthesis in green plants. [9] The structure of Photosystem II is remarkably similar to the bacterial reaction center, and it is theorized that they share a common ancestor. The core of Photosystem II consists of two subunits referred to as D1 and D2 ...

   President-elect Donald Trump has been a divisive, unpopular political figure for years, and he remains so. An analysis of 2024 exit polls show a clear divide based on what issues voters say most ...

8. PI curve - Wikipedia

   en.wikipedia.org/wiki/PI_Curve

   The PI (or photosynthesis-irradiance) curve is a graphical representation of the empirical relationship between solar irradiance and photosynthesis. A derivation of the Michaelis–Menten curve, it shows the generally positive correlation between light intensity and photosynthetic rate. It is a plot of photosynthetic rate as a function of light ...
