Entropy in Biological Definition

Biomechanics

... The basic postulates of continuum mechanics are conservation of linear and angular momentum, conservation of mass, conservation of energy, and the entropy inequality. Solids are usually modeled using a Lagrangian or reference coordinates, whereas fluids are often modeled using spatial or Eulerian ...

Cell membrane

... relies on a transport protein to provide a channel or bind to specific molecules. This spontaneous process decreases free energy, and increases entropy in a system. Unlike active transport, this process does not involve chemical energy ( ATP ). Active transport Typically moves molecules ...

Life

... words, that which makes decisions that result in the most future choices, or that which strives to keep its options open. A system converting entropy to negentropy , using flow of energy . Descent with modification: a "useful" characteristic A useful characteristic upon which to base a ...

Lipid

... an ordered "clathrate" cage around the dissolved nonpolar molecule. However, when the nonpolar molecules separate out from the polar liquid, the entropy (state of disorder) of the polar molecules in the liquid increases. This is essentially a form of phase separation, similar to the spontaneous ...

Osmosis

... on osmosis. Chemical potential When a solute is dissolved in a solvent, the random mixing of the two species results in an increase in the entropy of the system, which corresponds to a reduction in the chemical potential. For the case of an ideal solution the reduction in chemical potential ...
