Abstrakt: In this chapter, we describe detailed protocols for measuring high-resolution respirometry on mitochondria extracted from adult whole mouse heart using the Oroboros 2k-Oxygraph system. The method provides detailed procedures for the preparation of mitochondria and measurement of high-resolution respirometry in response to various respiration inhibitions. The method described in this chapter could discern the different respiration rate on mitochondria extracted from two spatially distinct mitochondrial subpopulations, subsarcolemmal mitochondria (SSM) and intermyofibrillar mitochondria (IFM). These approaches can easily be translated to other cells and tissues.
