D) Golgi apparatus.

Question

Quizplus · Accepted Answer

Precursor chemicals that form the building blocks for neurotransmitters are absorbed from the blood supply. These precursor chemicals are typically taken up by neurons through transport mechanisms on the cell surface, such as transporter proteins. Once inside the neuron, enzymes can convert these precursor chemicals into neurotransmitters that can be packaged into vesicles and released upon stimulation. The mitochondria, cell nucleus, and Golgi apparatus are all involved in various cellular processes but do not play a direct role in the uptake of precursor chemicals for neurotransmitter synthesis.
