  2. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Aerobic respiration requires oxygen (O 2) in order to create ATP. Although carbohydrates , fats and proteins are consumed as reactants , aerobic respiration is the preferred method of pyruvate production in glycolysis , and requires pyruvate to the mitochondria in order to be oxidized by the citric acid cycle .

  3. Glycolysis - Wikipedia

    en.wikipedia.org/wiki/Glycolysis

    Summary of aerobic respiration Glycolysis is the metabolic pathway that converts glucose ( C 6 H 12 O 6 ) into pyruvate and, in most organisms, occurs in the liquid part of cells (the cytosol ). The free energy released in this process is used to form the high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine ...

  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.

  5. 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 ...

  6. Electron transport chain - Wikipedia

    en.wikipedia.org/wiki/Electron_transport_chain

    In aerobic respiration, the flow of electrons terminates with molecular oxygen as the final electron acceptor. In anaerobic respiration, other electron acceptors are used, such as sulfate. In an electron transport chain, the redox reactions are driven by the difference in the Gibbs free energy of reactants and products.

  7. Oxidative phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Oxidative_phosphorylation

    In brown adipose tissue, regulated proton channels called uncoupling proteins can uncouple respiration from ATP synthesis. [96] This rapid respiration produces heat, and is particularly important as a way of maintaining body temperature for hibernating animals, although these proteins may also have a more general function in cells' responses to ...
