11 Questions
What is the main reason enzymes are chosen for biosensors?
Enzymes are natural proteins that catalyze a specific substrate
How do enzymes recognize their target analyte in a biosensor?
Enzymes recognize their target analyte through a lock-and-key mechanism
What are the main advantages of using enzymes as bioreceptors in biosensors?
Enzymes are highly selective, sensitive, and can be combined with different transduction mechanisms
What are the three main mechanisms of operation of enzyme-based bioreceptors in biosensors?
Conversion of the analyte, detection of analyte inhibition/activation, and modification of enzyme properties
How do enzymes compare to chemical reactions in biosensors?
Enzymes are more selective, sensitive, and faster acting than chemical reactions
What is the primary advantage of using enzymes as bioreceptors in biosensors?
They have specific binding capabilities and catalytic activity.
Which of the following statements about enzyme structure is true?
Some enzymes require only their amino acid residues for activity.
What happens to an enzyme's catalytic activity if its native protein conformation is disrupted?
The catalytic activity is destroyed.
What is the purpose of using enzyme-coupled receptors in biosensors?
To modify the recognition mechanisms of the biosensor.
Which of the following statements about enzyme cascades is true?
They are often used to enhance the enzymatic activity.
Which of the following components can act as a cofactor for an enzyme?
Inorganic ions like $Fe^{2+}$, $Mg^{2+}$, $Mn^{2+}$, or $Zn^{2+}$
Explore the role of enzymes as bioreceptor molecules in biosensor applications, focusing on their specific binding capabilities and catalytic activity. Understand how enzymes are used to amplify detection through catalytic reactions and learn about the unique characteristics of these bioreceptors.
