Question
The movement of ???across the membrane causes the electrical signal to move across the muscles, and when it meets a ????goes down into to cell and releases???into the ????from the terminal cisterne ??? binds to the ??? and slides the ????around, uncovering the active sites. If the myosin head have obtain enery from ???? they will reach up and pull on the ??? filament.
In order to relax the muscle, ???? pulls the ???? from the receptors, stopping the electrical signal and allowing ??? to be pumped out of the ????. This blocks the active sites and stops the myosin heads from pulling.
Explanation / Answer
The movement of action potential acroos the membrane causes the electrical signal to move across the muscle and when it meets a axon terminal goes down into the cell and releases ions into the synaptic cleft from the terminal cistrene of the muscle fiber and binds to the receptors and slides cells around uncovering the active sites. If the myosin head have obtain energy from the ATP molecules stored in mitochondria they reach up and pull on the actin filament. In order to relax the muscle myosin pulls the myosin molecules from the receptors stopping the electrical signal and allowing the ions to be pumped out of the muscle fiber. This blocks the active sites and stops the myosin heads from pulling.
