Questions and Answers
What is an allosteric enzyme?
What is an allosteric enzyme?
- An enzyme that binds to a site other than the active site, causing a change in its shape and activity (correct)
- An enzyme that has only one subunit
- An enzyme that only binds to the active site
- An enzyme that does not require any binding to function
What causes the unusual kinetic properties of many allosteric enzymes?
What causes the unusual kinetic properties of many allosteric enzymes?
- Their interaction with multiple subunits (correct)
- Their ability to bind to multiple active sites
- Their ability to change shape without binding to any molecule
- Their inability to bind to any molecule
How does binding of a molecule to an allosteric site affect the activity of the enzyme?
How does binding of a molecule to an allosteric site affect the activity of the enzyme?
- It increases the activity of the enzyme (correct)
- It decreases the activity of the enzyme
- It causes the enzyme to stop functioning
- It has no effect on the activity of the enzyme
