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,

Many MC proteins preferentially catalyze the exchange of one solute for another ().A variety of these substrate carrier proteins, which are involved in energy transfer, have been found in the inner membranes of mitochondria and other eukaryotic organelles such as the peroxisome and facilitate the transport of inorganic ions, nucleotides, amino acids, keto acids and cofactors across the 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 ...
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 outer membrane mitochondrial proteins carry out functions for mitochondrial biogenesis and integration between mitochondria and the cellular system. The outer membrane consists of two types of integral proteins, including proteins with transmembrane β-barrel and proteins with one or more α-helical membrane anchors. [5] [6]
Simplified structure of a mitochondrion. The intermembrane space (IMS) is the space occurring between or involving two or more membranes. [1] In cell biology, it is most commonly described as the region between the inner membrane and the outer membrane of a mitochondrion or a chloroplast.
