Questions: Reuptake of a neurotransmitter refers to A absorption of the neurotransmitter into the dendrites of the receiving neuron B absorption of the neurotransmitter into the terminal buttons of the sending neuron (C) release of the neurotransmitter by the soma of the originating neuron (D) the rate at which a neurotransmitter is created for use by a neuron

The answer is B: absorption of the neurotransmitter into the terminal buttons of the sending neuron.

Explanation for each option:

A. Absorption of the neurotransmitter into the dendrites of the receiving neuron - This is incorrect. Neurotransmitters are not absorbed by the dendrites; instead, they bind to receptors on the dendrites of the receiving neuron.

B. Absorption of the neurotransmitter into the terminal buttons of the sending neuron - This is correct. Reuptake is the process by which neurotransmitters are reabsorbed by the terminal buttons of the sending neuron after they have been released into the synaptic cleft. This process helps to clear the synapse and recycle neurotransmitters for future use.

C. Release of the neurotransmitter by the soma of the originating neuron - This is incorrect. Neurotransmitters are released from the terminal buttons, not the soma, which is the cell body of the neuron.

D. The rate at which a neurotransmitter is created for use by a neuron - This is incorrect. Reuptake does not refer to the creation of neurotransmitters but rather their reabsorption after they have been released.

In summary, reuptake is the process by which neurotransmitters are absorbed back into the terminal buttons of the sending neuron, making option B the correct choice.
