English: A diagram showing a mitochondrion of the eukaryotic cell. Mitochondria are organelles surrounded by membranes, distributed in the cytosol of most eukaryotic cells. Its main function is the conversion of potential energy of pyruvate molecules into ATP.

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,
Mitochondrial matrix has a pH of about 7.8, which is higher than the pH of the intermembrane space of the mitochondria, which is around 7.0–7.4. [5] Mitochondrial DNA was discovered by Nash and Margit in 1963. One to many double stranded mainly circular DNA is present in mitochondrial matrix. Mitochondrial DNA is 1% of total DNA of a cell.
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.
English: A simple diagram of a plant leaf cell, labelled with numbers. It shows the cytoplasm, nucleus, cell membrane, cell wall, mitochondria, permanent vacuole, and chloroplasts. Note going down the left the numbers are not sequential, this is to match the numbering on others in the series.
[5] [6] Simplified model of F O F 1-ATPase alias ATP synthase of E. coli. Subunits of the enzyme are labeled accordingly. Rotation engine of ATP synthase. Located within the thylakoid membrane and the inner mitochondrial membrane, ATP synthase consists of two regions F O and F 1. F O causes rotation of F 1 and is made of c-ring and subunits a ...
Currently, this "inside-out" hypothesis (which states that the alphaproteobacteria, the ancestral mitochondria, were engulfed by the blebs of an asgardarchaeon, and later the blebs fused leaving infoldings which would eventually become the endomembrane system) is favored more than the outside-in one (which suggested that the endomembrane system ...
