The presence of acetylcholinesterase in the synapse results in which of the following? a. inhibition of an action potential being generated in the skeletal muscle fiber b. increased binding of acetylcholine at the motor end plate c. increased release of ca2+ from the sr d. two of the above e. none of the above *i know it's not d because that's originally what i had picked but it was wrong.

The presence of Acetyl cholinesterase in the SR is A. inhibition of an action potential being generated in the skeletal muscle fiber.

It begins with the nerve action potential that eventually releases the ACH and then breaks down to esterase. After the breakdown it opens the sodium/calcium doors and depolarizes the postsynaptic membrane and FINALLY, the action potential happens within the muscle.
