What CBRNE agent inhibits the enzyme AChE allowing ACh to accumulate affecting the way cells transmit signals to the body?

What CBRNE agent inhibits the enzyme AChE allowing ACh to accumulate affecting the way cells transmit signals to the body?

• A. Virus
• B. Nerve
• C. Fungus
• D. Bacteria

Answer: (B)

When acetylcholinesterase is blocked, acetylcholine cannot be broken down, so it builds up at nerve and muscle junctions and continuously stimulates cholinergic receptors. Nerve agents are chemical threats that do exactly this, causing rapid, widespread disruption of nervous system signaling and a range of cholinergic symptoms. Viruses, fungi, and bacteria cause illness through infection or other toxic effects, not by inhibiting acetylcholinesterase. So the described agent is a nerve agent.
