Free energy definition biology
WebBiologists have identified various traits common to all the living organisms we know of. Although nonliving things may show some of these characteristic traits, only living things show all of them. 1. Organization. Living things are highly organized, meaning they contain specialized, coordinated parts. WebThe Gibbs free energy of a system at any moment in time is defined as the enthalpy of the system minus the product of the temperature times the entropy of the system. G = H - TS. The Gibbs free energy of the system is a state function because it is defined in terms of thermodynamic properties that are state functions.
