How many mitochondria are there in skeletal muscle?

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.
