  2. List of Schedule 3 substances (CWC) - Wikipedia

    en.wikipedia.org/wiki/List_of_Schedule_3...

    The Schedule 3 list is one of three lists. Chemicals which can be used as weapons, or used in their manufacture, but which have no, or almost no, legitimate applications as well are listed in Schedule 1, whilst Schedule 2 is used for chemicals which have legitimate small-scale applications. The use of Schedule 1, 2, or 3 chemicals as weapons is ...

  3. List of Schedule 1 substances (CWC) - Wikipedia

    en.wikipedia.org/wiki/List_of_Schedule_1...

    The Schedule 1 list is one of three lists. Chemicals which are feasible to use as weapons, and their precursors, but which have legitimate applications as well are listed in Schedule 2 (small-scale applications) and Schedule 3 (large-scale applications). The use of Schedule 1, 2, or 3 chemicals as weapons is banned by the Convention.

  4. 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.

  5. Light-dependent reactions - Wikipedia

    en.wikipedia.org/wiki/Light-dependent_reactions

    The electrons are transferred to plastoquinone and two protons, generating plastoquinol, which released into the membrane as a mobile electron carrier. This is the second core process in photosynthesis. The initial stages occur within picoseconds, with an efficiency of 100%. The seemingly impossible efficiency is due to the precise positioning ...

  6. Calvin cycle - Wikipedia

    en.wikipedia.org/wiki/Calvin_cycle

    The Calvin cycle thus happens when light is available independent of the kind of photosynthesis (C3 carbon fixation, C4 carbon fixation, and crassulacean acid metabolism (CAM)); CAM plants store malic acid in their vacuoles every night and release it by day to make this process work. [2]

  7. List of Schedule 2 substances (CWC) - Wikipedia

    en.wikipedia.org/wiki/List_of_Schedule_2...

    It may be used as a precursor in one of the chemical reactions at the final stage of formation of a chemical listed in Schedule 1 or Schedule 2, part b; It poses a significant risk to the object and purpose of this Convention by virtue of its importance in the production of a chemical listed in Schedule 1 or Schedule 2, part A;

  8. Photosynthetic reaction centre - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_reaction_centre

    This process of reducing quinone is comparable to that which takes place in the bacterial reaction center. Photosystem II obtains electrons by oxidizing water in a process called photolysis. Molecular oxygen is a byproduct of this process, and it is this reaction that supplies the atmosphere with oxygen.

  9. Heterogeneous water oxidation - Wikipedia

    en.wikipedia.org/wiki/Heterogeneous_Water_Oxidation

    This process occurs naturally in plants photosystem II to provide protons and electrons for the photosynthesis process and release oxygen to the atmosphere, [1] as well as in some electrowinning processes. [2] Since hydrogen can be used as an alternative clean burning fuel, there has been a need to split water efficiently.
