Distinct populations of mitochondria within a muscle cell have different functions and characteristics.

“So mito there are different types of mitochondria like the two types of ants. There's division of labor. There's some mitochondria for example in the muscle that are at the surface of the muscle like just underneath the saroma the the skin of the muscle cells and then there mitochondria that are inside you where the actin measin the contractile proteins happen subscar mitochondria and interophibrillary mitochondria two populations their proteom is different their their molecular composition of those different types of mitochondria are different their functions ATP synthesis reactive oxygen species production their ability to handle calcium and release calcium is different. Their morphology is very different. So even within one cell you get this uh division of labor and um uh differentiation of mitochondria”
