Multi-level organization of mitochondrial molecular composition, structures, functions, and signaling roles within the cell. These nested facets of mitochondrial functions are depicted hierarchically in a Maslow-type pyramidal fashion with the most basic determinants at the bottom and more complex and emergent elements above. These facets of mitochondria (first level) are regarded as determinants of higher-level physiological functions (second level), which in turn influence systems-level functions (third level) that contribute to clinical outcomes and mortality.
