Release of Acetylcholine: Signal at nerve terminal causes CA2+
... Biosynthesis: Choline is derived from “acetylcholine” after its hydrolysis by acetykcholinesterase or from the circulation. It is taken up into neurone by a high affinity, Na+- dependant, ATP requiring process. It is co-transported with Na+, and ATP is required to “pump” Na+ cations out of the neuro ...
