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 |
