Comment on the statement ‘living state is a non-equilibrium steady state to be able to perform work’.


Living organism are not in equilibrium because system at equilibrium cannot perform work. The living organisms exist in a Steady state characterised by concentration of each of the biomolecules.
These biomolecules are in a metabolic flux. Any chemical or physical ‘process moves simultaneously to equilibrium. As living organisms work continuously, they cannot afford to reach equilibrium. Hence, the living state is in a non-equilibrium steady-state to be able to perform work. This is achieved by energy input provided lay metobolism.
