Cardiolipin is a so called "double" lipid with four fatty acid tails that is abundant in this organelle. Thermogenin acts as an uncoupler of one process that occurs in these structures in brown fat cells, which get their color due to the abundance of these structures. The F1 complex of a protein found in this structure has been shown to be water soluable, and that protein's F0 complex is a transmembrane domain that releases its product onto the F1 complex. Cytochrome C is a peripheral protein found in the intermembrane space of this organelle, and secretion of that enzyme serves as a signal to trigger apoptosis. For 10 points, name this semi-autonomous organelle, where the bulk of ADP phosphorylation occurs, often called the "powerhouse of the cell."
