During transmission across a typical chemical synapse
A) neurotransmitter molecules are stored in the synaptic cleft.
B) action potentials trigger chemical changes that make the synaptic vesicles fuse with each other.
C) vesicles containing neurotransmitters diffuse to the receiving cell's plasma membrane.
D) neurotransmitter molecules bind to receptors in the receiving cell's plasma membrane.

Question

Quizplus · Accepted Answer

During transmission across a typical chemical synapse, neurotransmitter molecules released from the presynaptic neuron bind to receptors located on the postsynaptic neuron's plasma membrane. This binding causes a response in the postsynaptic neuron, allowing for the transmission of the signal across the synapse. Option A is incorrect because neurotransmitter molecules are stored in synaptic vesicles within the presynaptic neuron, not in the synaptic cleft. Option B is also incorrect because action potentials trigger the release of neurotransmitter molecules into the synaptic cleft, not the fusion of synaptic vesicles with each other. Option C is incorrect because vesicles containing neurotransmitters are released from the presynaptic neuron and diffuse across the synaptic cleft to bind to receptors on the postsynaptic neuron's plasma membrane.
