Mark the Incorrect statement 

1. Co-enzymes are also organic compounds but their association with apoenzyme is only transient

2. Vmax (maximum velocity) represent that there are no substrate molecules to bind with free enzyme molecule

3. Living state is non-equilibrium steady state to be able to perform work 

4. Enzymes eventually bring down the energy barrier making the transition of substrate to product more easy
