  2. Biological thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Biological_thermodynamics

    Biological thermodynamics (Thermodynamics of biological systems) is a science that explains the nature and general laws of thermodynamic processes occurring in living organisms as nonequilibrium thermodynamic systems that convert the energy of the Sun and food into other types of energy.

  3. List of types of equilibrium - Wikipedia

    en.wikipedia.org/wiki/List_of_types_of_equilibrium

    Partial equilibrium, the equilibrium price and quantity which come from the cross of supply and demand in a competitive market; Radner equilibrium, an economic concept defined by economist Roy Radner in the context of general equilibrium; Recursive competitive equilibrium, an economic equilibrium concept associated with a dynamic program

  4. File:Punctuated Equilibrium.pdf - Wikipedia

    en.wikipedia.org/.../File:Punctuated_Equilibrium.pdf

    English: Alternative explanations of the punctuated equilibrium pattern of evolution observed in the fossil record. Both macromutation and relatively rapid episodes of gradual evolution by natural selection could give the effect of apparently instantaneous change, since 10,000 years barely registers in the fossil record.

  5. Gibbs–Donnan effect - Wikipedia

    en.wikipedia.org/wiki/Gibbs–Donnan_effect

    Donnan equilibrium across a cell membrane (schematic). The Gibbs–Donnan effect (also known as the Donnan's effect, Donnan law, Donnan equilibrium, or Gibbs–Donnan equilibrium) is a name for the behaviour of charged particles near a semi-permeable membrane that sometimes fail to distribute evenly across the two sides of the membrane. [1]

  6. Law of mass action - Wikipedia

    en.wikipedia.org/wiki/Law_of_mass_action

    The law is a statement about equilibrium and gives an expression for the equilibrium constant, a quantity characterizing chemical equilibrium. In modern chemistry this is derived using equilibrium thermodynamics. It can also be derived with the concept of chemical potential. [3]

  7. Transition state theory - Wikipedia

    en.wikipedia.org/wiki/Transition_state_theory

    In 1884, Jacobus van 't Hoff proposed the Van 't Hoff equation describing the temperature dependence of the equilibrium constant for a reversible reaction: ⁡ = where ΔU is the change in internal energy, K is the equilibrium constant of the reaction, R is the universal gas constant, and T is thermodynamic temperature.

  8. Sedimentation equilibrium - Wikipedia

    en.wikipedia.org/wiki/Sedimentation_equilibrium

    The advantage of using analytical sedimentation equilibrium analysis for Molecular Weight of proteins and their interacting mixtures is the avoidance of need for derivation of a frictional coefficient, otherwise required for interpretation of dynamic sedimentation. Sedimentation equilibrium can be used to determine molecular mass.

  9. Stress (biology) - Wikipedia

    en.wikipedia.org/wiki/Stress_(biology)

    In biology, most biochemical processes strive to maintain equilibrium (homeostasis), a steady state that exists more as an ideal and less as an achievable condition. Environmental factors, internal or external stimuli, continually disrupt homeostasis; an organism's present condition is a state of constant flux moving about a homeostatic point ...
