Which mode of transppd,9lp;dy6b 8o;7 jbavcu r6rort do neurotra /4 tgktzb7t:z3fvsx/3fh k6y nsmitters use to travel across a synapse?
A. Facilitated diffusion
B. Active transport
C. Simple diffusion
D. Exocytosis
参考答案: C
本题详细解析:
Explanation: Neurotransmitters travel freely without energy from an area of high concentration at the presynaptic membrane to a low concentration at the postsynaptic membrane via simple diffusion, Choice C is correct. Choice A is incorrect, as neurotransmitters do not use a channel to diffuse across the synapse. Choice B is incorrect, as neurotransmitters do not travel against the concentration gradient using energy across the synapse. Choice D is incorrect as although neurotransmitters are released from the presynaptic membrane via exocytosis, they do not travel across the synapse using this method.
