What is the importance of acetylcholinesterase in muscle cell contraction?

Video transcript

Hi, everyone. Let's look at the next question. Which of the following is responsible for the termination of neuronal transmission. Choice. A myoglobin B, calcium ions C acetyl Collines trace or D acetycholine. Well, we can recall that that neuronal transmission is begun when the neuron releases acetylcholine into the synaptic cleft. The acetylcholine binds to receptors in the muscle fiber and then calcium ions began to flood and generating an action potential. So calcium ions and acetycholine which are B and D can be eliminated because they're responsible for the transmission of the action potential. And our question is asking us for the termination of that neuronal transmission. So we need to think about that. And we can think about if the acetylcholine being released and buy me the receptors is what's starting this whole cascade. Then we look at choice C acetyl colon Estrace, which would be an enzyme that breaks down acetylcholine as being our answer here responsible for the termination of the neuronal transmission. It breaks down any aceto colon, excuse me, any acetycholine that's left in the synaptic left, thereby stopping it from continuing to bind to those receptors and terminating the neuronal transmission. Should I say my globin is just completely not our answer choice that's responsible for the storage of oxygen in muscle tissue. So not even part of our picture here. So that one's easy to eliminate. So again, responsible for the termination of neuronal transmission. Try C acetyl colon Estrace. See you in the next video.
