  2. Quantum biology - Wikipedia

    en.wikipedia.org/wiki/Quantum_biology

    The effects of quantum coherence on EET in photosynthesis are best understood through state and process coherence. State coherence refers to the extent of individual superpositions of ground and excited states for quantum entities, such as excitons. Process coherence, on the other hand, refers to the degree of coupling between multiple quantum ...

  3. Photosynthetically active radiation - Wikipedia

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

    However, photosynthesis is a quantum process and the chemical reactions of photosynthesis are more dependent on the number of photons than the energy contained in the photons. Therefore, plant biologists often quantify PAR using the number of photons in the 400-700 nm range received by a surface for a specified amount of time, or the ...

  4. Quantum tunnelling - Wikipedia

    en.wikipedia.org/wiki/Quantum_tunnelling

    Quantum tunnelling is among the central non-trivial quantum effects in quantum biology. [33] Here it is important both as electron tunnelling and proton tunnelling. Electron tunnelling is a key factor in many biochemical redox reactions (photosynthesis, cellular respiration) as well as enzymatic catalysis.

  5. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    In general outline, photosynthesis is the opposite of cellular respiration: while photosynthesis is a process of reduction of carbon dioxide to carbohydrates, cellular respiration is the oxidation of carbohydrates or other nutrients to carbon dioxide. Nutrients used in cellular respiration include carbohydrates, amino acids and fatty acids.

  6. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    The following is a breakdown of the energetics of the photosynthesis process from Photosynthesis by Hall and Rao: [6]. Starting with the solar spectrum falling on a leaf, 47% lost due to photons outside the 400–700 nm active range (chlorophyll uses photons between 400 and 700 nm, extracting the energy of one 700 nm photon from each one)

  7. Quantum Aspects of Life - Wikipedia

    en.wikipedia.org/wiki/Quantum_Aspects_of_Life

    Quantum Aspects of Life, a book published in 2008 with a foreword by Roger Penrose, explores the open question of the role of quantum mechanics at molecular scales of relevance to biology. The book contains chapters written by various world-experts from a 2003 symposium and includes two debates from 2003 to 2004; giving rise to a mix of both ...

  8. Kautsky effect - Wikipedia

    en.wikipedia.org/wiki/Kautsky_effect

    The quantum yield of photosynthesis, which is also the photochemical quenching of fluorescence, is calculated through the following equation: Φ p = (F m-F 0)/F m = F v /F m. F 0 is the low fluorescence intensity, which is measured by a short light flash that is not strong enough to cause photochemistry, and thus induces fluorescence.

  9. Compensation point - Wikipedia

    en.wikipedia.org/wiki/Compensation_point

    The CO 2 compensation point (Γ) is the CO 2 concentration at which the rate of photosynthesis exactly matches the rate of respiration. There is a significant difference in Γ between C 3 plants and C 4 plants: on land, the typical value for Γ in a C 3 plant ranges from 40–100 μmol/mol, while in C 4 plants the values are lower at 3–10 μmol/mol. Plants with a weaker CCM, such as C2 ...
