Question: What is the role of allosteric sites in enzyme regulation?

Options:

1. To bind substrates
2. To bind inhibitors only
3. To bind activators or inhibitors that change enzyme shape
4. To increase the temperature of the reaction

Correct Answer: To bind activators or inhibitors that change enzyme shape

Solution:

Allosteric sites are regions on enzymes where molecules can bind, causing a change in the enzyme\'s shape and activity, thus regulating its function.
