After nervous stimulation stops,what prevents ACh in the synaptic cleft from continuing to stimulate contraction?
A) the tropomyosin blocking the myosin once full contraction is achieved
B) acetylcholinesterase destroying the ACh
C) calcium ions returning to the terminal cisternae
D) the action potential stops going down the overloaded T tubules

Question

Quizplus · Accepted Answer

Acetylcholinesterase breaks down ACh in the synaptic cleft, preventing continued stimulation of contraction. The other options may be involved in the regulation of muscle contraction, but they do not specifically prevent ACh from continuing to stimulate contraction.
