Answer:
Binding of <u>ACh (acetylcholine) </u> to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.
Explanation:
It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.
Hence , the answer is <u>ACh (acetylcholine) .</u>
Answer:Genetic information are transferred from nucleus to cytoplasm of cell through RNA. In eukaryotic cells, once precursor mRNA (pre-mRNA) has been transcribed from DNA, it is processed to mature mRNA. This removes its introns, non-coding sections, of the pre-mRNA.
