Which of the following correctly describes the role of SNARE proteins in neurotransmitter release?

SNARE proteins actively transport neurotransmitters against their concentration gradient.

SNARE proteins mediate the fusion of vesicles with the plasma membrane, allowing neurotransmitter release via exocytosis.

SNARE proteins facilitate the passive diffusion of neurotransmitters across the synaptic cleft.

SNARE proteins are involved in receptor-mediated endocytosis of neurotransmitters.
