  2. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Cellular respiration is the process by which biological fuels are broken down in the presence of a hydrogen acceptor, such as oxygen, to drive the production of adenosine triphosphate (ATP), which stores chemical energy in a biologically accessible form.

  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

    The change of Gibbs free energy (ΔG) in an exergonic reaction (that takes place at constant pressure and temperature) is negative because energy is lost (2). In chemical thermodynamics, an exergonic reaction is a chemical reaction where the change in the free energy is negative (there is a net release of free energy). [1]

  7. Adenosine triphosphate - Wikipedia

    en.wikipedia.org/wiki/Adenosine_triphosphate

    Adenosine triphosphate (ATP) is a nucleoside triphosphate [2] that provides energy to drive and support many processes in living cells, such as muscle contraction, nerve impulse propagation, and chemical synthesis. Found in all known forms of life, it is often referred to as the "molecular unit of currency" for intracellular energy transfer. [3]

  8. Respiration - Wikipedia

    en.wikipedia.org/wiki/Respiration

    Cellular respiration, the process in which nutrients are converted into useful energy in a cell . Anaerobic respiration, cellular respiration without oxygen; Maintenance respiration, the amount of cellular respiration required for an organism to maintain itself in a constant state

  9. Phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Phosphorylation

    Phosphorylation is essential to the processes of both anaerobic and aerobic respiration, which involve the production of adenosine triphosphate (ATP), the "high-energy" exchange medium in the cell. During aerobic respiration, ATP is synthesized in the mitochondrion by addition of a third phosphate group to adenosine diphosphate (ADP) in a ...
