Question 6 0.5 pts The "docking" of a synaptic vesicle at the active zone inside an axon terminal is an important step in making the synaptic vesicle available for release. The docking process involves which of the following events? the neurotransmitter molecules bind to postsynaptic recept O molecules of neurotransmitter are actively transported inside the synaptic vesicle the synaptic vesicle membrane fuses with the synaptic membrane and ruptures O vesicle-associated membrane proteins linking together with proteins associated with the presynaptic...

Which statement about synapse is TRUE? a. neurotransmitters are released by the presynaptic cell and absorbed by the postsynaptic cell b. all of these. c. In a synapse, electrical signal is converted to chemical signal then convert back to electrical signal d.the presynaptic cell and postsynaptic cell are connected by tight junctions.

Consider the neuromuscular junction between a pre-synaptic neuron and the diaphragm muscle. Acetylcholine is a neurotransmitter that is released from the presynaptic neuron to induce muscle contraction in the post-synaptic muscle cell. Which of the following would be an effect of tetrodotoxin? A. More acetylcholine in the synapse of the neuromuscular junction with the diaphragm B. Less acetylcholine in the synapse of the neuromuscular junction with the diaphragm

29. The effects of acetylcholine can be either excitatory or inhibitory. The effect depends on A. the type of calcium channels in the presynaptic neuron B. the type of acetylcholine-activated channel in the post-synaptic membrane C. the presence or absence of acetylcholinesterase in the synaptic cleft D. whether the presynaptic cell is excitatory or inhibitory E. whether calcium flows through the acetylcholine-activated channel.

Passage IV (Questions 114-117) Electrical impubses are transferred from one neuron to another via a synapse. Synapses can be electrical or chemical. In response to an electrical stimalus such as an action potential the presynaptic neuron in a chemical synapse releases a neuro- transmitner across a small space between the two neurons known as a symaptic cief. Neurotransmitiers may have excita- ory...
