Problem: The effects of acetylcholine can be either excitatory or inhibitory. The effect depends on A. The type of calcium channels in the presynaptic neuron.B. The type of acetylcholine-activated channel in the post-synaptic membrane.C. The presence or absence of acetylcholinesterase in the synaptic cleft.D. whether the presynaptic cell is excitatory or inhibitory.E. whether calcium flows through the acetylcholine-activated channel.

FREE Expert Solution

Acetylcholine is vital for many functions, including muscle stimulation and memory formation. There are two general mechanisms for its signaling pathway: one is excitatory, such as its induction to produce EPSP; the other is inhibitory, such as the reduction of the heart's pumping rate.
