Mitochondrial structure. Computer artwork of a section through a mitochondrion,showing the internal structure and a loop of mitochondrial DNA (deoxyribonucleic acid,mtDNA),the organelle's genetic material,at its centre. Mitochondria are a type of organelle found in the cytoplasm of eukaryotic cells. They oxidase sugars and fats to produce energy. A mitochondrion has two membranes,a smooth outer membrane and a folded inner membrane. The folds of the inner membrane are called cristae,and it is here that the chemical reaction to produce energy takes place. Unlike other eukaryotic DNA,mtDNA is circular. Due to this it is thought that mitochondria were once free-living,but were incorporated into eukaryotic cells under a process known as | |
