- They inhibit enzyme activity.
- They change the enzyme's primary structure.
A: They enhance enzyme function.

Q: How does temperature affect enzyme activity?
- It has no effect on enzyme activity.
- It can lead to enzyme denaturation at extreme temperatures.
- It only increases enzyme activity.

A: Oxidoreductases

Q: Why is the Michaelis-Menten equation important in enzyme kinetics?
- It describes the structure of enzymes.
- It explains the process of enzyme denaturation.
- It relates reaction rate to substrate concentration.

A: It relates reaction rate to substrate concentration.

Q: How can students apply their knowledge of enzyme kinetics in a laboratory setting?
- By memorizing enzyme structures.
- By conducting experiments to measure reaction rates.
- By reading theoretical texts only.
- By avoiding hands-on experiments.
A: By conducting experiments to measure reaction rates.

Q: What is allosteric regulation in enzymes?
- Binding of substrates at the active site.
- Binding of regulatory molecules at sites other than the active site.
- Permanent changes to the enzyme structure.
- The process of enzyme denaturation.
A: Binding of regulatory molecules at sites other than the active site.

Q: Which type of enzyme inhibition involves a molecule competing with the substrate for the active site?
- Non-competitive inhibition
