018 Agonists and Antagonists

In this video, Leslie Samuel explains the concepts of agonists and antagonists in biology. Agonists are molecules that mimic the effects of neurotransmitters, while antagonists oppose these effects. The video provides examples such as succinylcholine as an agonist and purari as an antagonist, illustrating how they interact with receptors in the body. The video concludes with an invitation for questions and further discussion.

Describe how the antagonist purari interacts with acetylcholine.

What are the potential consequences of an antagonist binding to receptor sites?
