15 Questions
What is the result of enzyme inhibition?
A loss of catalytic activity of an enzyme
What can enzyme inhibitors do to the protein structure of an enzyme?
Change the protein structure of an enzyme
What type of enzyme inhibitors are there?
Both competitive and noncompetitive inhibitors
What can be a characteristic of the effects of some inhibitors?
Sometimes irreversible
What are molecules that prevent enzymes from catalyzing reactions called?
Inhibitors
What is the effect of increasing substrate concentration on an inhibited enzyme?
It reverses the effect of inhibition
What is the term for inhibition that occurs when the inhibitor binds somewhere other than the active site?
Noncompetitive inhibition
How does noncompetitive inhibition affect the enzyme's shape?
It changes the enzyme's shape, decreasing its activity
What happens when an enzyme is inhibited through covalent binding?
The inhibition is irreversible
What is the result of decreasing the concentration of a noncompetitive inhibitor?
The enzyme's activity increases
What is the result of an inhibitor forming a covalent bond with an enzyme?
The inhibition is permanent
What is the key difference between competitive and noncompetitive inhibition?
The location of inhibitor binding
What type of inhibition occurs when an inhibitor binds covalently to an enzyme?
Irreversible inhibition
What is the characteristic of inhibition when an inhibitor covalently binds to an enzyme?
It is irreversible
What happens to the enzyme when an inhibitor forms a covalent bond with it?
The enzyme is permanently inhibited
