2. Calvin cycle - Wikipedia

   en.wikipedia.org/wiki/Calvin_cycle

   The Calvin cycle, light-independent reactions, bio synthetic phase, dark reactions, or photosynthetic carbon reduction (PCR) cycle [1] of photosynthesis is a series of chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose. The Calvin cycle is present in all photosynthetic eukaryotes and also many ...

3. Photosynthesis - Wikipedia

   en.wikipedia.org/wiki/Photosynthesis

   Photosynthesis measurement systems are not designed to directly measure the amount of light the leaf absorbs, but analysis of chlorophyll fluorescence, P700- and P515-absorbance, and gas exchange measurements reveal detailed information about, e.g., the photosystems, quantum efficiency and the CO 2 assimilation rates.

4. Fractionation of carbon isotopes in oxygenic photosynthesis

   en.wikipedia.org/wiki/Fractionation_of_carbon...

   Carbon on Earth naturally occurs in two stable isotopes, with 98.9% in the form of 12 C and 1.1% in 13 C. [1] [8] The ratio between these isotopes varies in biological organisms due to metabolic processes that selectively use one carbon isotope over the other, or "fractionate" carbon through kinetic or thermodynamic effects. [1]

5. 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 ...

6. Melvin Calvin - Wikipedia

   en.wikipedia.org/wiki/Melvin_Calvin

   Melvin Ellis Calvin (April 8, 1911 – January 8, 1997) [3] was an American biochemist known for discovering the Calvin cycle along with Andrew Benson and James Bassham, for which he was awarded the 1961 Nobel Prize in Chemistry.

7. Chlorophyll a - Wikipedia

   en.wikipedia.org/wiki/Chlorophyll_a

   Chlorophyll a is very important in the energy phase of photosynthesis. Two electrons need to be passed to an electron acceptor for the process of photosynthesis to proceed. [5] Within the reaction centers of both photosystems there are a pair of chlorophyll a molecules that pass electrons on to the transport chain through redox reactions. [20]

9. Thylakoid - Wikipedia

   en.wikipedia.org/wiki/Thylakoid

   The thylakoid lumen is a continuous aqueous phase enclosed by the thylakoid membrane. It plays an important role for photophosphorylation during photosynthesis. During the light-dependent reaction, protons are pumped across the thylakoid membrane into the lumen making it acidic down to pH 4.
