Signaling at synapses is usually terminated by:
A)calcium influx.
B)potassium influx.

D)degradation or reuptake of neurotransmitters.

Question

Quizplus · Accepted Answer

Signaling at synapses is terminated by degradation or reuptake of neurotransmitters. This is necessary to prevent continuous signaling and allow for new signals to be transmitted. Calcium and potassium influx can be involved in the termination of signaling in some cases, but they are not the primary mechanism. Inhibitory neurotransmitters can prevent signaling but do not terminate ongoing signaling.
