Assuming a synapse is excitatory, which of the following would tend to strengthen a synapse? a. A drug that enhances reuptake of the transmitter b. An antagonist to the receptor c. A drug that blocks calcium entry into the presynaptic terminal d. A drug that inhibits an enzyme in the synaptic cleft that degrades the neurotransmitter

Respuesta :

Answer:

C

Explanation:

calcium ions stimulate the release of acetylcholine

Excitatory synapse is defined as the in which the positive action potential is caused in the neurons and cells.

The correct answer is:

Option D. A drug that inhibits an enzyme in the synaptic cleft that degrades the neurotransmitter

Excitatory synapse can be explained as:

1. Excitatory synapse will be determined by the neurotransmitter if it is released from the presynaptic neuron. The neurotransmitter will inhibit or excite the receiving neuron.

2. The synapse can be strengthened by the drug that inhibits the synaptic cleft that degrades the neurotransmitter. The calcium influx triggers the synaptic vesicles to bind to the presynaptic membrane.

3. The action potential causes the release of ACh into the synaptic cleft that causes the conformational change in the membrane channels.

Thus, the correct answer is Option C.
