Role of enzyme in reactions is to:
1. Decrease activation energy
2. Increase activation energy
3. Act as an inorganic catalyst
4. None of the above
Which of the following statements regarding enzyme inhibition is correct:
1. | Competitive inhibition is seen when a substrate competes with an enzyme for binding to an inhibitor protein |
2. | Non-competitive inhibitors often bind to the enzyme irreversibly |
3. | Competitive inhibition is seen when the substrate and the inhibitor compete for the active site on the enzyme |
4. | Non-competitive inhibition of an enzyme can be overcome by adding large amounts of substrate |
The catalytic efficiency of two different enzymes can be compared by the:
1. The Km value
2. The pH optimum value
3. Molecular size of the enzyme
4. Formation of the product
