Verify Activity #2
• You are an exotic animal vet. Your favorite
patient, the banded sea krait, is back! You decide
to collect venom from the krait and you isolate
alpha-bungarotoxin (a nicotinic ACh receptor
antagonist).
a) If you applied alpha-bungarotoxin directly to the
sympathetic ganglia of autonomic nerves
leading to the heart, what would happen to
heart rate?
