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.

Hope this <em><u>Helped!</u></em> :D
Answer:
Voluntary muscles mean under conscious control and skeletal muscle is consciously controlled, unlike involuntary muscle, the ly are controlled by the autonomic nervous system.
For population to be healthy, factors such as food nutrients water and space must be available, limiting factors include low food supply and lack of space. Limiting factors can lower birth rates increase death rates or lead to emigration
Yes it is you have to use it in order to creat or make one .
Aerobic respiration occurs in the presence of oxygen producing a lot of energy, carbon dioxide and water. ... The energy released due to the breakdown of sugar molecule is stored in ATP. Each ATP molecule gives 7200 calories of energy. This energy is stored in the form of phosphate bonds.
