What ions, ATP, and neurotransmitters are used in muscle contraction and where are they used??
vivado [14]

Answer:

Hiya there!

Explanation:

ATP then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site. ATP can then attach to myosin, which allows the cross-bridge cycle to start again; further muscle contraction can occur.

acetylcholine : Skeletal muscle contraction and changes with exercise. (A) Neurotransmitter (acetylcholine, ACh) released from nerve endings binds to receptors (AChRs) on the muscle surface.

The muscle contraction cycle is triggered by calcium ions binding to the protein complex troponin, exposing the active-binding sites on the actin. As soon as the actin-binding sites are uncovered, the high-energy myosin head bridges the gap, forming a cross-bridge.

All movement are locomotion but not all locomotion are movement​
Vladimir [108]
Some may assume that movement and locomotion are the same, but these two words have certain differences. Movement is known to be the time when a living organism will move from one place to another. Locomotion means that the movement that the living organism did has made changes to the current position of the organism.
