What are mitochondria

Question

What are mitochondria? What is the fundamental morphology of such organelles and in which cells they can be found?

Answer 1

Mitochondria are the organelles in which the most significant part of the cellular respiration takes place is the ATP production.

Mitochondria are organelles surrounded by two lipid membranes. The inner membrane invaginates to interior of the organelle forming cristae which delimitate the internal space termed as mitochondrial matrix and where mitochondrial DNA (that is, mtDNA), mitochondrial RNA (that is, mt RNA), mitochondrial ribosomes and respiratory enzymes can be found. Mitochondria are many in eukaryotic cells and they are even more plentiful in such cells which use more energy, such as muscle cells. Since they have their own DNA, ribosomes and RNA, mitochondria can self-replicate.
