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. Metabolic pathway - Wikipedia

   en.wikipedia.org/wiki/Metabolic_pathway

   [1]: 26 In most cases of a metabolic pathway, the product of one enzyme acts as the substrate for the next. However, side products are considered waste and removed from the cell. [2] Different metabolic pathways function in the position within a eukaryotic cell and the significance of the pathway in the given compartment of the cell. [3]

5. 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 .

6. 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 ...

7. 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.
