<P> The most prominent roles of mitochondria are to produce the energy currency of the cell , ATP ( i.e. , phosphorylation of ADP ) , through respiration , and to regulate cellular metabolism . The central set of reactions involved in ATP production are collectively known as the citric acid cycle , or the Krebs cycle . However , the mitochondrion has many other functions in addition to the production of ATP . </P>
