It depends on the type of skeletal muscle. Slow and fast oxidative fibers (type I and type IIa) may have many mitochondria. Fast glycolytic fibers (type IIx/IIb) have very few mitochondria. This is because in fast glycolytic fibers (type IIx/IIb) ATP can be produced outside of the mitochondrion in the cytosol of the cell due to high concentrations of glycolytic enzymes present in these fibers. In contrast, in oxidative fibers ATP is produced mostly within the mitochondrion, so more mitochondria are needed to to produce large amounts of ATP.
Also, the number of mitochondria in these cells can increase with adaptations to exercise conditioning.

Normal skeletal muscle has what percent mitochondria?
12 percent of the volume of skeletal muscle.
Why do same cells contain many mitochondria?
Skeletal muscle cells, for instance, contain many mitochondria because the energy consumed in the contraction of the sarcomere is enormous. Skin cells, for instance, contain much less mitochondria as the cellular work the need to do is minimal compared to skeletal muscle cells.
What organelle is found in large numbers in a skeletal muscle cell?
mitochondia is greater in number in skeletal muscle cells.
Do cardiac muscle cells contain more mitochondria than skeletal muscle cells?
Both are very active.But skeletal muscles have more.
Skeletal muscle fibers differ from typical cells in that these muscle fibers?
Skeletal muscle fibers differ from typical cells in that these muscle fibers have many nuclei. The skeletal muscle store calcium ions in the sarcoplasmic reticulum.
Does cardiac muscle have more mitochondria and depend less on a continual supply of oxygen than does skeletal muscle?
no
Who do active cells have large numbers of mitochondria?
Skeletal muscle cells,cardiac muscle cells,sperm cells
Why do you think skeletal muscle contains more mitochondria than other cells?
microbioglogy
What percentage of cardiac muscle is made up of mitochondria?
As per Marieb (2007) 25%, as apposed to 2% in skeletal muscle.
What is the innermost part of the muscle?
There are two types of muscle in the body. The Cardiac Muscle and the Skeletal Muscle. The skeletal muscle is made up of intrafusal and extrafusal fibers. The Muscle Belly is made up entirely of extrafusal fibers (even in the deepest parts). The intrafusal fibers are located throughout the muscle. The cardiac muscle is distinct from skeletal muscle, one of the main differences is the amount of mitochondria it has is increased, and so technically at the deepest part of cardiac muscle is mitochondria (but there are other components as well).
What are found in skeletal muscles?
Nuclei - Because of its development. Mitochondria - ATP is needed to make the muscle move.
How many mitochondria does a skin cell have?
Cells that require the most energy contain the most energy generating mitochondria. The cells of the brain, the skeletal muscle and heart muscle, and the eye contain the highest number of mitochondria (as many as 10,000 per cell) while the skin cells, which do not require much energy, contain only a few hundred of them.
