What happens to choline after acetylcholine is hydrolyzed?

Explanation:
Choline is recycled by being actively transported back into the presynaptic nerve terminal and reused to make more acetylcholine. After acetylcholine is hydrolyzed in the synaptic cleft, choline is taken up by a high-affinity choline transporter and, inside the neuron, choline acetyltransferase combines it with acetyl-CoA to form acetylcholine again for packaging into vesicles. This recycling is essential for sustained cholinergic signaling. The other ideas aren’t correct because choline isn’t converted into dopamine, it doesn’t just diffuse away and become inactive, and monoamine oxidase does not act on choline.
