Reuptake refers to the
A
the ending of the refractory period.
B
movement of neurotransmitter molecules across a synaptic gap.
C
inflow of positively charged ions through an axon membrane.
D
reabsorption of excess neurotransmitter molecules by a sending neuron.
Explanation: 

Detailed explanation-1: -Reuptake is the reabsorption of a neurotransmitter by a neurotransmitter transporter located along the plasma membrane of an axon terminal (i.e., the pre-synaptic neuron at a synapse) or glial cell after it has performed its function of transmitting a neural impulse.

Detailed explanation-2: -Reuptake. Excess neurotransmitters in the synapse are reabsorbed into the sending neurons through the process of reuptake.

Detailed explanation-3: -n. the process by which neurotransmitter molecules that have been released at a synapse are reabsorbed by the presynaptic neuron that released them.

Detailed explanation-4: -Reuptake is what happens after a signal is transmitted: The neurotransmitter, its “work” completed, is reabsorbed back into the cell that previously released it.

Detailed explanation-5: -reuptake. noun. re·up·take (ˈ)rē-ˈəp-ˌtāk. : the reabsorption by a neuron of a neurotransmitter following the transmission of a nerve impulse across a synapse.
