Question

Curare, a poison from a South American shrub, blocks the binding of ACh by muscle cells. What would happen to muscle function if a toxic dose of curare entered the bloodstream?

Spasm: The muscle cell will run out of ATP and fluid, becoming hyperexcitable and developing uncontrolled forceful contractions

Seizure: A sudden surge of electrical activity in the brain would cause muscles to stiffen and tremble

No effect: Muscle function is not dependent on the binding of acetylcholine

Paralysis: Action potentials would be impeded at the neuromuscular junction, and the nerve would be unable to trigger the muscle to act
