  2. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Typical eukaryotic cell. Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor, such as oxygen, to drive the bulk production of adenosine triphosphate (ATP), which contains energy. Cellular respiration may be described as a set of metabolic reactions and processes that take ...

  3. Carbon–hydrogen bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–hydrogen_bond

    Carbon–hydrogen bond. In chemistry, the carbon–hydrogen bond (CH bond) is a chemical bond between carbon and hydrogen atoms that can be found in many organic compounds. [1] This bond is a covalent, single bond, meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells ...

  4. Respiration (physiology) - Wikipedia

    en.wikipedia.org/wiki/Respiration_(physiology)

    Ventilation refers to the in-and-out movement of air of the lungs and perfusion is the circulation of blood in the pulmonary capillaries. [1] In mammals, physiological respiration involves respiratory cycles of inhaled and exhaled breaths. Inhalation (breathing in) is usually an active movement that brings air into the lungs where the process ...

  5. Carbon–hydrogen bond activation - Wikipedia

    en.wikipedia.org/wiki/Carbon–hydrogen_bond...

    In organic chemistry and organometallic chemistry, carbon–hydrogen bond activation (CH activation) is a type of organic reaction in which a carbon–hydrogen bond is cleaved and replaced with a C−X bond (X ≠ H is typically a main group element, like carbon, oxygen, or nitrogen). Some authors further restrict the term CH activation ...

  6. Redox - Wikipedia

    en.wikipedia.org/wiki/Redox

    Cellular respiration, for instance, is the oxidation of glucose (C 6 H 12 O 6) to CO 2 and the reduction of oxygen to water. The summary equation for cell respiration is: C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O + Energy. The process of cell respiration also depends heavily on the reduction of NAD + to NADH and the reverse reaction (the ...

  7. Oxidative phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Oxidative_phosphorylation

    Oxidative phosphorylation (UK / ɒkˈsɪd.ə.tɪv /, US / ˈɑːk.sɪˌdeɪ.tɪv / [1]) or electron transport-linked phosphorylation or terminal oxidation is the metabolic pathway in which cells use enzymes to oxidize nutrients, thereby releasing chemical energy in order to produce adenosine triphosphate (ATP).

  8. Carbohydrate catabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_catabolism

    Carbohydrate catabolism. Digestion is the breakdown of carbohydrates to yield an energy-rich compound called ATP. The production of ATP is achieved through the oxidation of glucose molecules. In oxidation, the electrons are stripped from a glucose molecule to reduce NAD+ and FAD. NAD+ and FAD possess a high energy potential to drive the ...

  9. Cellular waste product - Wikipedia

    en.wikipedia.org/wiki/Cellular_waste_product

    Simplified Theoretical Reaction: C 6 H 12 O 6 (aq) + 6O 2 (g) → 6CO 2 (g) + 6H 2 O (l) + ~ 30ATP Cells undergoing aerobic respiration produce 6 molecules of carbon dioxide, 6 molecules of water, and up to 30 molecules of ATP (adenosine triphosphate), which is directly used to produce energy, from each molecule of glucose in the presence of ...
