2. Cellular respiration - Wikipedia

   en.wikipedia.org/wiki/Cellular_respiration

   Cellular respiration is the process of oxidizing biological fuels using an inorganic electron acceptor, such as oxygen, to drive production of adenosine triphosphate (ATP), which contains energy. Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to transfer chemical ...

3. Oxygen - Wikipedia

   en.wikipedia.org/wiki/Oxygen

   Oxygen also acts as a ligand for transition metals, forming transition metal dioxygen complexes, which feature metal– O 2. This class of compounds includes the heme proteins hemoglobin and myoglobin. [131] An exotic and unusual reaction occurs with PtF 6, which oxidizes oxygen to give O 2 + PtF 6 −, dioxygenyl hexafluoroplatinate. [132]

4. Respiration (physiology) - Wikipedia

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

   The process of breathing does not fill the alveoli with atmospheric air during each inhalation (about 350 ml per breath), but the inhaled air is carefully diluted and thoroughly mixed with a large volume of gas (about 2.5 liters in adult humans) known as the functional residual capacity which remains in the lungs after each exhalation, and ...

   5. Stay Hydrated. Staying hydrated is essential for keeping your body and mind feeling energized. Water plays a critical role in many bodily functions, including transporting oxygen and building ...

6. Allotropes of oxygen - Wikipedia

   en.wikipedia.org/wiki/Allotropes_of_oxygen

   Singlet oxygen is the common name used for the two metastable states of molecular oxygen (O 2) with higher energy than the ground state triplet oxygen. Because of the differences in their electron shells, singlet oxygen has different chemical and physical properties than triplet oxygen, including absorbing and emitting light at different ...

7. Diatomic molecule - Wikipedia

   en.wikipedia.org/wiki/Diatomic_molecule

   While the study of vibrational energy level of the diatomic molecules can be described using the harmonic oscillator approximation or using the quantum vibrational interaction potentials. [12] [13] These potentials give more accurate energy levels because they take multiple vibrational effects into account.

8. Work of breathing - Wikipedia

   en.wikipedia.org/wiki/Work_of_breathing

   The normal relaxed state of the lung and chest is partially empty. Further exhalation requires muscular work. Inhalation is an active process requiring work. [4] Some of this work is to overcome frictional resistance to flow, and part is used to deform elastic tissues, and is stored as potential energy, which is recovered during the passive process of exhalation, Tidal breathing is breathing ...

9. Aerobic organism - Wikipedia

   en.wikipedia.org/wiki/Aerobic_organism

   4: Microaerophiles need oxygen because they cannot ferment or respire anaerobically. However, they are poisoned by high concentrations of oxygen. They gather in the upper part of the test tube but not the very top. 5: Aerotolerant organisms do not require oxygen as they metabolise energy anaerobically. Unlike obligate anaerobes however, they ...
