Question

Quizplus · Accepted Answer

ACh is primarily deactivated by enzymes, specifically acetylcholinesterase (AChE), which breaks down ACh into choline and acetate. This process occurs in the synaptic gap, allowing for the efficient recycling and reuse of choline in the presynaptic neuron for the synthesis of new ACh. Reuptake mechanisms and astrocytes are not involved in the deactivation of ACh. While diffusion can occur, it is a less efficient mechanism for deactivation compared to enzymatic breakdown.
