Answer:
<u>acetylcholine</u>
Explanation:
In the pre-synaptic knob there are vesicles which contain a transmitter substance called acetylcholine. When an impulse reaches the synaptic knob, it stimulates the vesicles to move towards the pre-synaptic membrane releasing the acetylcholine.
The transmitter substance makes the membrane permeable. The neuromuscular junction contains the sensory neurone(afferent), motor neurones(efferent) and the relay neurones(connector).
Pepsin is one of three principal protein-degrading enzymes in the
digestive system, the other two being chymotrypsin and trypsin. During
the process of digestion, these enzymes collaborate to break down
dietary proteins to their components, i.e., peptides and amino acids.
