What occurs during reuptake?Multiple ChoiceA neurotransmitter that has already been released into the synaptic cleft is taken back into the presynaptic neuron.A neuropeptide breaks down into amino acids, which act as neurotransmitters.An action potential reverses direction.An enzyme breaks down a neurotransmitter and then another enzyme builds it back up.

Which statement describes a possible outcome for a neurotransmitter after release into the synaptic cleft?Group of answer choicesActivation of G-protein-coupled receptor on postsynaptic cellModulation by an enzyme, increasing its efficiencyReuptake into postsynaptic terminal via transporter proteinsActivation of voltage-gated ion channel on presynaptic cellUptake into postsynaptic cell via endocytosis

Neurotransmitters are released in a synapse and bind to:

Determine what happens to the neurotransimitter after it binds to the receiving membrane receptors.Multiple ChoiceIt is reabsorbed by the sending membrane.It degrades due to the lack of calcium.It stays bound to the receiving membrane.It is released back into the synaptic cleft where it builds up.

When a neurotransmitter is released into the synaptic cleft, the response of the receiving neuron will be toward excitation.Group startsTrue or FalseTrue, unselectedFalse, unselected
