Cellular respiration is the process of oxidizing biological fuels using an inorganic electron acceptor, such as oxygen, to drive production of adenosine triphosphate (ATP), which contains energy. Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to transfer chemical ...

The metabolic pathway in the cell is regulated by covalent or non-covalent modifications. A covalent modification involves an addition or removal of a chemical bond, whereas a non-covalent modification (also known as allosteric regulation) is the binding of the regulator to the enzyme via hydrogen bonds , electrostatic interactions, and Van der ...
Cellular respiration takes place in the cristae of the mitochondria within cells. Depending on the pathways followed, the products are dealt with in different ways. CO 2 is excreted from the cell via diffusion into the blood stream, where it is transported in three ways: Up to 7% is dissolved in its molecular form in blood plasma.
A metabolic network is the complete set of metabolic and physical processes that determine the physiological and biochemical properties of a cell.As such, these networks comprise the chemical reactions of metabolism, the metabolic pathways, as well as the regulatory interactions that guide these reactions.
Glucose regulation and product use are the primary categories in which these pathways differ between organisms. [2] In some tissues and organisms, glycolysis is the sole method of energy production. [2] This pathway is common to both anaerobic and aerobic respiration. [1] Glycolysis consists of ten steps, split into two phases. [2]
The ten-step catabolic pathway of glycolysis is the initial phase of free-energy release in the breakdown of glucose and can be split into two phases, the preparatory phase and payoff phase. ADP and phosphate are needed as precursors to synthesize ATP in the payoff reactions of the TCA cycle and oxidative phosphorylation mechanism. [ 4 ]
Illustration of the malate–aspartate shuttle pathway. The malate–aspartate shuttle (sometimes simply the malate shuttle) is a biochemical system for translocating electrons produced during glycolysis across the semipermeable inner membrane of the mitochondrion for oxidative phosphorylation in eukaryotes.
