What is the turnover number in enzyme kinetics?
What is the turnover number in enzyme kinetics?
- The time it takes for an enzyme to saturate with substrate
- The rate at which the product is converted to the substrate
- The stability of the enzyme-substrate complex
- The number of substrate molecules converted to product in a given unit of time on a single enzyme molecule (correct)
What happens if a competitive inhibitor is removed from the system?
What happens if a competitive inhibitor is removed from the system?
- The enzyme remains inactive
- The action of the enzyme is fully restored (correct)
- The Vmax of the reaction increases
- The binding affinity between substrate and enzyme decreases
What is the impact of competitive inhibition on Km and Vmax?
What is the impact of competitive inhibition on Km and Vmax?
- Km increases, Vmax remains the same
- Both Km and Vmax decrease
- Km increases, Vmax decreases (correct)
- Km decreases, Vmax remains the same
