The Neurotransmitter Involved in the Process of Contraction in Skeletal

Question

The neurotransmitter involved in the process of contraction in skeletal muscles is ________.
A) ATP
B) acetylcholine
C) troponin
D) globulin
E) serotonin

Accepted Answer

Acetylcholine is the neurotransmitter that is released at the neuromuscular junction and binds to receptors on the surface of skeletal muscle fibers, initiating a series of events that lead to muscle contraction. ATP is involved in providing energy for muscle contractions, but it is not a neurotransmitter. Troponin and globulin are proteins involved in muscle contraction but are not neurotransmitters. Serotonin is not directly involved in skeletal muscle contraction.
