Suppose That Acetylcholine Binds Its Receptor on the Surface of a Muscle

Question

Suppose that acetylcholine binds its receptor on the surface of a muscle cell. What happens next?
A) A sodium gate opens.
B) G protein is activated.
C) Tyrosine is phosphorylated.
D) Tyrosine kinase is activated.
E) A neurotransmitter crosses the synapse.

Accepted Answer

When acetylcholine binds its receptor on the surface of a muscle cell, it typically leads to the opening of a sodium gate. This allows sodium ions to flow into the muscle cell, initiating a sequence of events that eventually results in muscle contraction.
