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. 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 ]

4. Cellular waste product - Wikipedia

   en.wikipedia.org/wiki/Cellular_waste_product

   Cellular waste products are formed as a by-product of cellular respiration, a series of processes and reactions that generate energy for the cell, in the form of ATP. One example of cellular respiration creating cellular waste products are aerobic respiration and anaerobic respiration .

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; Breathing, passing air in and out ...

6. 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.

7. Maintenance respiration - Wikipedia

   en.wikipedia.org/wiki/Maintenance_respiration

   Maintenance respiration in plants refers to the amount of cellular respiration, measured by the carbon dioxide (CO 2) released or oxygen (O 2) consumed, during the generation of usable energy (mainly ATP, NADPH, and NADH) and metabolic intermediates used for (i) resynthesis of compounds that undergo renewal (turnover) in the normal process of metabolism (examples are enzymatic proteins ...
