  2. Primary nutritional groups - Wikipedia

    en.wikipedia.org/wiki/Primary_nutritional_groups

    [1] The terms aerobic respiration, anaerobic respiration and fermentation (substrate-level phosphorylation) do not refer to primary nutritional groups, but simply reflect the different use of possible electron acceptors in particular organisms, such as O 2 in aerobic respiration, or nitrate (NO − 3), sulfate (SO 2

  3. Obligate aerobe - Wikipedia

    en.wikipedia.org/wiki/Obligate_aerobe

    [1] [2] In this type of respiration, oxygen serves as the terminal electron acceptor for the electron transport chain. [1] Aerobic respiration has the advantage of yielding more energy ( adenosine triphosphate or ATP ) than fermentation or anaerobic respiration , [ 3 ] but obligate aerobes are subject to high levels of oxidative stress .

  4. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    [1] Cellular respiration is a vital process that occurs in the cells of all living organisms. [2] [better source needed] Respiration can be either aerobic, requiring oxygen, or anaerobic; some organisms can switch between aerobic and anaerobic respiration. [3] [better source needed]

  5. Respiration (physiology) - Wikipedia

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

    Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the diffusion and transport of metabolites between the organism and the external environment.

  6. Aerobic organism - Wikipedia

    en.wikipedia.org/wiki/Aerobic_organism

    An aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment. [1] The ability to exhibit aerobic respiration may yield benefits to the aerobic organism, as aerobic respiration yields more energy than anaerobic respiration. [2] Energy production of the cell involves the synthesis of ATP by an enzyme called ...

  7. Cellular waste product - Wikipedia

    en.wikipedia.org/wiki/Cellular_waste_product

    [1] [2] 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 ...

  8. Ecosystem respiration - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_respiration

    Ecosystem respiration is the sum of all respiration occurring by the living organisms in a specific ecosystem. [1] The two main processes that contribute to ecosystem respiration are photosynthesis and cellular respiration. Photosynthesis uses carbon-dioxide and water, in the presence of sunlight to produce glucose and oxygen whereas cellular ...

  9. Obligate anaerobe - Wikipedia

    en.wikipedia.org/wiki/Obligate_anaerobe

    2) and hydrogen peroxide (H 2 O 2) within cells. [1] A reaction between these two products results in the formation of a free hydroxyl radical (OH.). [4] Superoxide, hydrogen peroxide, and hydroxyl radicals are a class of compounds known as reactive oxygen species (ROS), highly reactant products that are damaging to microbes, including obligate ...
