In humans, which cell type would typically contain a higher number of mitochondria: a skeletal muscle cell or a skin (epidermal) cell?
A
Skin (epidermal) cell, because it performs more oxidative phosphorylation than muscle
B
Both cell types contain the same number of mitochondria because mitochondria number is fixed per cell type
C
Neither; human cells generally lack mitochondria and rely on cytosolic ATP production
D
Skeletal muscle cell, because it has higher ATP demand for contraction
