Final answer:
The structure/composition of a vSNARE is a proteinaceous complex. The structure/composition of a tSNARE is also a proteinaceous complex.
Step-by-step explanation:
The structure/composition of a vSNARE is a proteinaceous complex. vSNARE stands for vesicle soluble N-ethylmaleimide-sensitive factor attachment protein receptor. It is a protein complex found on the surface of synaptic vesicles. The vSNARE plays a key role in the fusion of the vesicle with the target membrane during neurotransmitter release.
The structure/composition of a tSNARE is also a proteinaceous complex. tSNARE stands for target soluble N-ethylmaleimide-sensitive factor attachment protein receptor. It is a protein complex found on the target membrane. The tSNARE helps in the fusion of the vesicle with the target membrane during neurotransmitter release, by interacting with the vSNARE.
