Practice: Muscarinic acetylcholine receptors (mAchRs) are on cells throughout the body. Pilocarpine is a drug that binds and activates mAchRs. On mAchRs, pilocarpine is a (choose all that apply):

Practice: Muscarinic acetylcholine receptors (mAchRs) are on cells throughout the body. Atropine is a drug that binds and blocks (does not activate) mAchRs. On mAchRs, atropine is a (choose all that apply):
