6. How does the action of a non competitive inhibitor slow down reaction rate?
Molecules of inhibitor compete for the allosteric site
Molecules of substrate 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 active site.
7. What word is used to describe a chemical which decreases the rate of a reaction?
inhibitor
active site
substrate
enzyme
8. When simple molecules are built up into more complex molecules.
anabolic reaction
metabolism
catabolic reaction
degradation
9. All the biochemical reactions that occur within a living cell.
metabolism
anabolic
respiration
reactions
10. How does the enzyme ensure that two substrates will combine in a biosynthetic reaction
The active site holds the substrates in the correct orientation in an induced fit.
the active site holds the inhibitor in the correct orientation in an induced fit.
The enzyme holds the substrates in the correct orientation in an induced fit.
The active site holds the substrates in the correct order in an induced fit.
11. How does a competitive inhibitor slow down the reaction rate?
Molecules of inhibitor don't fit 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
When molecules of inhibitor bind to the allosteric site, changing the shape of the active site.
12. what term is used to describe that an enzyme can only act on one substrate. The active site is a complementary shape to the substrate.
specific
special
inhibitor
active site
13. which type of reaction requires energy?
anabolic
degradation
catabolic
enzyme controlled
14. 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 an inhibitor 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.
15. What is the relationship between increasing substrate concentration and reaction rate.
As the substrate concentration increases the reaction rate decreases.
As the substrate concentration increases the reaction rate increases.
As the substrate concentration decreases the reaction rate increases.
As the substrate concentration decreases the reaction rate decreases.
