  2. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    The process of photosynthesis provides the main input of free energy into the biosphere, and is one of four main ways in which radiation is important for plant life. [114] The radiation climate within plant communities is extremely variable, in both time and space.

  3. 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)

  4. 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 ...

  5. Autotroph - Wikipedia

    en.wikipedia.org/wiki/Autotroph

    Plants can only use a fraction (approximately 1%) of this energy for photosynthesis. [11] The process of photosynthesis splits a water molecule (H 2 O), releasing oxygen (O 2) into the atmosphere, and reducing carbon dioxide (CO 2) to release the hydrogen atoms that fuel the metabolic process of primary production. Plants convert and store the ...

  6. Photoautotroph - Wikipedia

    en.wikipedia.org/wiki/Photoautotroph

    Photoautotrophs are organisms that can utilize light energy from sunlight and elements (such as carbon) from inorganic compounds to produce organic materials needed to sustain their own metabolism (i.e. autotrophy). Such biological activities are known as photosynthesis, and examples of such organisms include plants, algae and cyanobacteria.

  7. Ecological efficiency - Wikipedia

    en.wikipedia.org/wiki/Ecological_efficiency

    Out of a total of 28,400 terawatt-hours (96.8 × 10 ^ 15 BTU) of energy used in the US in 1999, 10.5% was used in food production, [3] with the percentage accounting for food from both producer and primary consumer trophic levels. In comparing the cultivation of animals versus plants, there is a clear difference in magnitude of energy efficiency.

  9. Carbohydrate metabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_metabolism

    During the second phase, chemical energy from the intermediates is transferred into ATP and NADH. [2] The breakdown of one molecule of glucose results in two molecules of pyruvate, which can be further oxidized to access more energy in later processes. [1] Glycolysis can be regulated at different steps of the process through feedback regulation.
