| energy coupling | <chemistry> The tranfer of energy produced in one reaction to another. (09 Oct 1997) |
|---|---|
| excitation contraction coupling | <physiology> Name given to the chain of processes coupling excitation of a muscle by the arrival of a nervous impulse at the motor end plate to the contraction of the filaments of the sarcomere. The crucial link is the release of calcium from the sarcoplasmic reticulum and the analogy is often drawn between this and stimulus secretion coupling, that also involves calcium release into the cytoplasm. (18 Nov 1997) |
| fixed coupling | Where several premature beats are seen, the interval between each of them and the preceding normal beat is constant. Synonym: constant coupling. Variable coupling, where several extrasystoles are seen, the interval between each of them and the preceding sinus beat varies. (05 Mar 2000) |
| basal metabolism | <biochemistry, biology> Heat production, or its measurement, of an organism at the lowest level of cell chemistry in an inactive, awake, fasting state. It may be determined directly by means of a calorimeter or indirectly by calculating the heat production from an analysis of the end products of oxidation within the organism or from the amount of oxygen utilised. (27 Jun 1999) |
| calcium metabolism | A set of biochemical processes which act to keep the level of calcium in the blood at a constant level, with enough around to build bones and teeth. (09 Oct 1997) |
| calcium metabolism disorders | Disorders in the processing of calcium in the body: its absorption, transport, storage, and utilization. (12 Dec 1998) |
| carbohydrate metabolism | <biochemistry> The breakdown of starches and sugars into smaller units that can be used by the body for energy. (27 Sep 1997) |
| respiratory metabolism | The exchange of respiratory gases in the lungs, oxidation of foodstuffs in the tissues, and production of carbon dioxide and water. (05 Mar 2000) |
| metabolism | <biochemistry> The sum of all the physical and chemical processes by which living organised substance is produced and maintained (anabolism) and also the transformation by which energy is made available for the uses of the organism (catabolism). Origin: Gr. Metaballein = to turn about, change, alter (18 Nov 1997) |
| phosphorus metabolism disorders | Disorders in the processing of phosphorus in the body: its absorption, transport, storage, and utilization. (12 Dec 1998) |
| water of metabolism | The water formed in the body by oxidation of the hydrogen of the food, the greatest amount being produced in the metabolism of fat (about 117 g/100 g of fat). Synonym: water of combustion. (05 Mar 2000) |
| Crassulacean acid metabolism | <plant biology> Physiological adaptation of certain succulent plants, in which carbon dioxide can be fixed (nonphotosynthetically) at night into malic and other acids. During the day the carbon dioxide is regenerated and then fixed photosynthetically into the Calvin Benson cycle. This adaptation permits the stomata to remain closed during the day, conserving water. (18 Nov 1997) |
| primary metabolism | Metabolic processes central to most cells; e.g., biosynthesis of macromolecules, energy production, turnover, etc. (05 Mar 2000) |
| protein metabolism | Decomposition and synthesis of protein in the tissues. Synonym: proteometabolism. (05 Mar 2000) |
| xenobiotic metabolism | <biochemistry> This is the sum of the physical and chemical changes that affect foreign substances in living organisms from uptake to excretion. (09 Oct 1997) |
