The cell of the muscle tissue shorten to exert force. These tissues will support movement of the various muscles in the by exerting force.
Doubtful. One would think that any glycogen stored in muscle cells would be producing mitochondrial ATP for use in the sarcomere, the muscle contraction unit.
Contraction.
the amount of ATP in the muscle cells
Skeletal muscle cells are very thin, and lean. They are designed for contraction and expansion.
ATP
Because the energetic demands could be high, especially in red fibers with a lot of mitochondria and haemoglobin. They need to convert glicose to ATP to shorten and in muscle contraction and lengthen as well.
movement
pacemaker cells
Muscle tissue contracts or shortens, allowing movement.
Muscles move by contraction. When the cells shorten, the muscle pulls on the ligaments that connect the bones and the movable body parts. Depending on how a skeletal muscle acts, it may be classified as a flexor (decreases angle to joint) or an extensor (increases angle, straightening the joint).
