Answer:

The paralyzing effect of curare is caused by its ability to block the action of acetylcholine at neuron-muscle synapses.

Explanation:

Curare -used by South American Indians to attack their enemies and hunting- is considered a poison, that really is a chemical agent with paralyzing, neurotoxic, activity on skeletal muscle.

Curare is extracted from various plants -including <em>Strychnos toxifera</em> and <em>Anomospermum grandiflora</em>- or synthesized as D-tubocurarine.

The effect of curare is on the nicotinic receptors found in the neuromotor plate.

  • Acetylcholine binds to its receptor at the neuromuscular synapse to promote the opening of the sodium channels required by the muscle fiber to contract.
  • The neurotoxin blocks the receptors, preventing the action of the neurotransmitter acetylcholine, which induces muscle paralysis.

High doses of the neurotoxin can cause death from respiratory paralysis.
