Question

A hunter in a South American jungle uses the poisonous drug curare on the tip of his arrow. When the arrow strikes an animal, it almost instantly goes limp and quickly suffocates because its respiratory system has become paralyzed. The curare has _____ the neurotransmitter acetylcholine.

a) Increased the production of
b) Inhibited the release of
c) Enhanced the sensitivity to
d) Accelerated the breakdown of

Answer 1

Curare inhibits the release of acetylcholine, causing muscle paralysis and suffocation in animals.

Step-by-step explanation:

Curare, a poisonous drug used by hunters in the South American jungle, acts by inhibiting the release of the neurotransmitter acetylcholine. When the arrow with the curare-tipped arrow strikes an animal, the curare interferes with nerve impulses, preventing the release of acetylcholine. This leads to flaccid paralysis of muscles and ultimately causes quick suffocation as the respiratory system becomes paralyzed.
