  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. Exergonic reaction - Wikipedia

    en.wikipedia.org/wiki/Exergonic_reaction

    An exergonic reaction (such as cellular respiration) is a reaction that releases free energy in the process of the reaction. The progress of the reaction is shown by the line. Activation energy (1) slows down the reaction.

  5. 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

  6. Aerobic organism - Wikipedia

    en.wikipedia.org/wiki/Aerobic_organism

    Aerobic organisms use a process called aerobic respiration to create ATP from ADP and a phosphate. Glucose (a monosaccharide ) is oxidized to power the electron transport chain: [ 8 ] This equation is a summary of what happens in three series of biochemical reactions: glycolysis , the Krebs cycle (also known as the Citric acid cycle ), and ...

  7. Respiratory center - Wikipedia

    en.wikipedia.org/wiki/Respiratory_center

    Absence of the center results in an increase in depth of respiration and a decrease in respiratory rate. The pneumotaxic center regulates the amount of air that can be taken into the body in each breath. The dorsal respiratory group has rhythmic bursts of activity that are constant in duration and interval. [11]

  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. Respiratory system - Wikipedia

    en.wikipedia.org/wiki/Respiratory_system

    In humans and other mammals, the anatomy of a typical respiratory system is the respiratory tract.The tract is divided into an upper and a lower respiratory tract.The upper tract includes the nose, nasal cavities, sinuses, pharynx and the part of the larynx above the vocal folds.
