  2. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from nutrients into ATP, and then release waste products. [1] Cellular respiration is a vital process that occurs in the cells of all [[plants and some bacteria ]].

  3. Bioenergetics - Wikipedia

    en.wikipedia.org/wiki/Bioenergetics

    Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...

  4. 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. Chemiosmosis - Wikipedia

    en.wikipedia.org/wiki/Chemiosmosis

    Chemiosmosis is the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient.An important example is the formation of adenosine triphosphate (ATP) by the movement of hydrogen ions (H +) across a membrane during cellular respiration or photosynthesis.

  7. Biophysics - Wikipedia

    en.wikipedia.org/wiki/Biophysics

    Medical biophysics is a field closely related to physiology. It explains various aspects and systems of the body from a physical and mathematical perspective. Examples are fluid dynamics of blood flow, gas physics of respiration, radiation in diagnostics

  8. Respiration - Wikipedia

    en.wikipedia.org/wiki/Respiration

    Maintenance respiration, the amount of cellular respiration required for an organism to maintain itself in a constant state; Respiration (physiology), transporting oxygen and carbon dioxide between cells and the external environment Respiratory system, the anatomical system of an organism used for respiration; Breathing, passing air in and out ...

  9. Adenosine diphosphate - Wikipedia

    en.wikipedia.org/wiki/Adenosine_diphosphate

    Oxidative phosphorylation produces 26 of the 30 equivalents of ATP generated in cellular respiration by transferring electrons from NADH or FADH2 to O 2 through electron carriers. [10] The energy released when electrons are passed from higher-energy NADH or FADH2 to the lower-energy O 2 is required to phosphorylate ADP and once again generate ...
