Organophosphates (used as pesticides and as biological weapons) are
 
  a. agonists that promote ACh production.
 b. antagonists that block ACh release.
 c. agonists that interfere with acetylcholinesteras e.
  d. antagonists that block ACh receptors.

Question 2

Sarin gas is a type of organophosphate. It was released in a Tokyo subway in 1995 by a religious sect, killing 12 people. Organophosphates are dangerous because they
 
  a. prevent the reuptake of acetylcholine (ACh), reducing the amount available for subsequent signaling.
  b. stimulate an larger than normal release of acetylcholine (ACh), leading to convulsions and death.
 c. interfere with acetylcholinesteras e (AChE), allowing acetylcholine (ACh) to overstimulate muscle fibers.
  d. occupy receptor sites for acetylcholine (ACh), preventing further signaling and paralyzing muscles.
