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

• Equilibrium is the state of stability, in which work done is assumed to be zero.

• As biological system always performs tasks, it is considered to be in inequilibrium.

• In biological system, metabolic reactions always remain on and influx and efflux of metabolites takes place constantly, hence it can be said that living state is a non-equilibrium steady state which is able to perform work.
