Detailed explanation-1: -Nerve cells release neurotransmitters across gaps and secretion of proteins and wastes:Facilitated Diffusion. Endocytosis.

Detailed explanation-2: -Neurotransmitter release occurs through the process of regulated exocytosis, in which a synaptic vesicle releases its contents in response to an increase in calcium. The use of genetic, biochemical, structural, and functional studies has led to the identification of factors important in the synaptic vesicle life cycle.

Detailed explanation-3: -Exocytosis is the fusion of secretory vesicles with the plasma membrane and results in the discharge of vesicle content into the extracellular space and the incorporation of new proteins and lipids into the plasma membrane.

Detailed explanation-4: -Proteins such as soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNAREs) and Rabs (Ras-like in rat brain) and Rabs-related proteins are some of the key proteins involved in exocytosis.

Detailed explanation-5: -Exocytosis is the general mechanism by which many hormones, transmitters, enzymes, and other special proteins and peptides are secreted from cells.
