Essential Biochemistry - Neurotransmitters (Section 1 - No. 29)
What process happens during the repolarization of the muscle membrane in the mechanism of action of acetylcholine?
Opening of the Na+ channels
A influx of Na+ ions
A influx of K+ ions
A release of acetylcholine
Објашњење
During the action potential, the Na+ channels open allowing Na+ to enter the neuron and then repolarization leads to K+ efflux
