Choline acetyltransferase is an enzyme that produces the neurotransmitter acetylcholine in cholinergic neurons. Acetylcholine is important for muscle contraction, heart rate regulation, and learning. The enzyme is produced in the rough endoplasmic reticulum and moves through the axon to the axon terminal, where it produces acetylcholine. Acetyl-CoA plays a crucial role in the process. The […]
