Quiz zum Vortrag
What explains the difference between the Fisher lock and key model and Koshland induced fit model?
- The induced-fit model is a dynamic theory that suggests conformational changes occur during the binding process.
- The lock and key model is a dynamic theory that suggests conformational changes occur during the binding process.
- The induced-fit model suggests atrophy favors enzyme and substrate interaction.
- The lock and key model suggests the protein substrate is a dynamic molecule.
- The induced-fit model suggests a strict ATP requirement for enzyme and substrate interaction.
Which of the following enzymes, in the human body, act at the fastest rate?
- Carbonic anhydrase
- Acetylcholinesterase
- Fumarase
- Lysozyme
- DNA Polymerase I
What is the turnover number of an enzyme?
- The maximum number of chemical conversions of the substrate molecules executed by an enzyme per second (at a given enzyme concentration).
- The minimum number of chemical conversions of the substrate molecules executed by an enzyme per second (at a given enzyme concentration).
- The minimum number of chemical conversions of the substrate molecules executed by an enzyme per minute (at a given enzyme concentration).
- The maximum number of chemical conversions of the substrate molecules executed by an enzyme per hour (at a given enzyme concentration).
- The maximum number of chemical conversions of the substrate molecules executed by an enzyme per minute (at a given enzyme concentration).
