The mitochondria contains its own set of DNA used to produce proteins found in the electron transport chain. The mitochondrial DNA only codes for about thirteen proteins that are used in processing mitochondrial transcripts, ribosomal proteins , ribosomal RNA , transfer RNA , and protein subunits found in the protein complexes of the electron ...
Mitochondria may have a number of different shapes. [24] A mitochondrion contains outer and inner membranes composed of phospholipid bilayers and proteins. [20] The two membranes have different properties. Because of this double-membraned organization, there are five distinct parts to a mitochondrion: The outer mitochondrial membrane,
Ribbon diagram of myoglobin bound to haem (sticks) and oxygen (red spheres) (Ribbon diagrams, also known as Richardson diagrams, are 3D schematic representations of protein structure and are one of the most common methods of protein depiction used today. The ribbon depicts the general course and organisation of the protein backbone in 3D and ...

Proteins can associate to form protein complexes, these often contain a set of proteins with similar functions, such as enzymes that carry out several steps in the same metabolic pathway. [43] This organization can allow substrate channeling , which is when the product of one enzyme is passed directly to the next enzyme in a pathway without ...
A crista (/ ˈ k r ɪ s t ə /; pl.: cristae) is a fold in the inner membrane of a mitochondrion.The name is from the Latin for crest or plume, and it gives the inner membrane its characteristic wrinkled shape, providing a large amount of surface area for chemical reactions to occur on.
A diagram showing mtDNA (circular) and mitochondrial ribosomes among other mitochondria structures. The mitochondrial ribosome, or mitoribosome, is a protein complex that is active in mitochondria and functions as a riboprotein for translating mitochondrial mRNAs encoded in mtDNA. The mitoribosome is attached to the inner mitochondrial membrane ...
The TIM/TOM complex is a protein complex in cellular biochemistry which translocates proteins produced from nuclear DNA through the mitochondrial membrane for use in oxidative phosphorylation. In enzymology , the complex is described as an mitochondrial protein-transporting ATPase ( EC 7.4.2.3 ), or more systematically ATP phosphohydrolase ...
