Other questions in this quiz
2. How does a competitive inhibitor slow down the reaction rate?
- Molecules of inhibitor don't fit the active site
- When molecules of inhibitor bind to the allosteric site, changing the shape of the active site.
- Molecules of inhibitor compete for the active site with the substrate.
- Molecules of substrate compete for the active site with the enzyme
3. How does the action of a non competitive inhibitor slow down reaction rate?
- Molecules of substrate compete for the active site.
- Molecules of inhibitor compete for the active site.
- Molecules of inhibitor bind to a different site on the enzyme, changing the shape of the active site. The substrate will no longer fit the active site.
- Molecules of inhibitor compete for the allosteric site
4. What word is used to describe a chemical which decreases the rate of a reaction?
- substrate
- enzyme
- inhibitor
- active site
5. Why will the reaction rate plateau despite the substrate concentration still increasing?
- The substrate concentration has become a limiting factor as all the active sites are occupied.
- The enzyme concentration has become a limiting factor as all the active sites are occupied.
- The enzyme concentration has become a limiting factor as all the active sites are free.
- The enzyme concentration has become an inhibitor as all the active sites are occupied.
