Mitochondria are the in which
the important part of cellular
respiration occurs: ATP production.

Mitochondria organelles delimited by
lipid membranes. The
membrane invaginates to interior of
the forming cristae that
the internal space as
mitochondrial matrix where
mitochondrial DNA (),
mitochondrial RNA (mt ),mitochondrial
ribosomes and respiratory
can be found. are
numerous in cells and they
even more abundant those cells
that more energy, like cells.
Because they their own DNA,
and ribosomes, mitochondria self replicate.
