| 4. | All of these |
Which of the following is incorrect?
| 1. | Enzymatic activity is maximum at its optimim pH and temperature. |
| 2. | Enzymatic activity declines both below and above the optimum value. |
| 3. | Low temperatures destroys enzymatic activity |
| 4. | High temperatures destroys enzymatic activity |
km (Michaelis constant) value of enzyme is the substrate concentration at which velocity of reaction
| 1. | Vmax | 2. | one fourth of Vmax |
| 3. | One third of Vmax | 4. | half of Vmax |
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 |
