Measure of a system's ability to do work. It is defined by F = U - TS, where U is the internal energy. For a reversible isothermal process, [delta]F represents the useful work available. 2, record 1, English, - free%20energy
Record number: 1, Textual support number: 1 CONT
Reactions that release a large quantity of free energy are those that have a very large negative [delta]G and create much disorder. Such reactions will have a strong tendency to occur, although the rate at which they do so will depend on other factors, such as the availability of specific enzymes. Conversely, reactions with a positive value of [delta]G create net order in the universe and cannot occur spontaneously. Such energetically unfavorable reactions will happen only if they are coupled to a second reaction with a negative [delta]G so large that the [delta]G of the entire process is negative. 3, record 1, English, - free%20energy

Fonction d'état d'un système à l'équilibre, notée souvent F et égale à U - TS, où U est l'énergie interne, T la température et S l'entropie du système. (Lors d'une transformation isotherme, la variation de cette énergie est égale au travail reçu par le système.) 2, record 1, French, - %C3%A9nergie%20libre
Record number: 1, Textual support number: 1 CONT
Notons que l'enzyme ne détermine pas le sens de la réaction; la proportion de molécules X et Y, à l'équilibre, dépend de facteurs thermodynamiques : la réaction favorisée est celle qui minimise ce que l'on appelle l'énergie libre. (L'énergie libre d'un système est égale à son énergie totale diminuée de son entropie, c'est-à-dire d'une quantité qui caractérise le désordre du système.) 3, record 1, French, - %C3%A9nergie%20libre
Record number: 1, Textual support number: 1 OBS
Pour caractériser une réaction, on parle aussi de variation d'enthalphie libre [delta]G = [delta]U + P[delta]V - T[delta]S où P est la pression et [delta]V, la variation de volume. En biochimie, on peut admettre que [delta]V = 0, car les variations de volume pour les réactions ayant lieu en solution sont négligeables. Ainsi, [delta]G = [delta]U - T[delta]S = [delta]F. Par conséquent [delta]F se confond avec [delta]G. Ceci est vrai surtout si les réactions font intervenir des liquides et des solides en solution (et aucun gaz) aux températures physiologiques qui sont basses. 4, record 1, French, - %C3%A9nergie%20libre

Chez la plupart des plantes, la respiration est aérobique, car elle utilise l'oxygène de l'air dans le processus de l'oxydation des aliments (surtout des glucides et lipides). La respiration aérobique a un fort rendement énergétique [...] Les produits finaux de la respiration aérobique sont le gaz carbonique, l'eau et l'énergie. 2, record 3, French, - respiration%20a%C3%A9robie

La respiration aboutit à la formation de composés uniquement minéraux et se traduit dans le cas de la respiration aérobie par une absorption d'oxygène et un rejet de gaz carbonique; elle est essentiellement due à l'activité des mitochondries. 4, record 3, French, - respiration%20a%C3%A9robie
