False
Fill in the blank: Agonists can be categorized into _____ and _____ agonists.
full, partial
What is a full agonist?
A full agonist is a drug that fully activates the receptor to elicit a maximal biological response.
What is a partial agonist?
A partial agonist is a drug that activates the receptor but produces a less than maximal response compared to a full agonist.

True or False: Agonists can only be naturally occurring substances.
False
Multiple Choice: Which of the following is NOT a characteristic of agonists? A) They bind to receptors, B) They inhibit receptor activity, C) They produce a biological response.
