10 Questions
What is the function of enzymes?
They speed up chemical reactions without being changed themselves
What is a characteristic of enzymes' structure?
They have a defined amino acid sequence
How much faster can enzymes typically increase the speed of a reaction?
106-10^14 times faster
What does it mean for enzymes to be stereospecific?
The reaction produces a single product
Are enzymes reusable?
Yes, once an enzyme binds to a substrate and catalyzes the reaction, it is released unchanged
What is an enzyme a substance that speeds up a chemical reaction and is changed by the reaction?
False
Enzymes have a defined threedimensional structure.
True
Enzymes increase the speed of a reaction typically by 10^6-10^14 times faster than the rate of the uncatalyzed reaction.
True
Enzymes are always specific to a single substrate.
False
Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is changed and cannot be used for another reaction.
False
