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

    Answer:

                      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 movessimultaneously to equilibrium. As living organisms work continuously, they cannot afford toreach equilibrium. Hence, the living state is in a non-equilibrium steady-state to be able toperform work. This is achieved by energy input provided lay metabolism.
