A protein found in the mitochondria that exists in two forms. The first form prevents the mitochondrial membrane from destabilizing. When mtCK is inactivated by free radicals, it transforms to the second form, making the membrane less stable.
According to the endosymbiotic theory, mitochondria might have been the remnants of early bacteria engulfed by ancient eukaryotic cells a billion years ago that might have evolved and become energy-yielding structures within eukaryotic cells at ...
Mitochondria
Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP).
Mitochondria Structure
Mitochondria have two membranes (not one as in other organelles). The outer membrane covers the organelle and contains it. The inner membrane folds over many times (cristae).
Mitochondria
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
Mitochondria are a major source of superoxide, formed by the one-electron reduction of oxygen during electron transport. Superoxide initiates oxidative damage to phospholipids, proteins and nucleic acids.
Mitochondrial targeting peptide
The N-terminal mitochondrial targeting peptide (mtTP) allows for the protein to be imported into the mitochondrion.

mitochondrial matrix
The compartment of the mitochondrion enclosed by the inner membrane and containing enzymes and substrates for the Krebs cycle.

Mitochondrial Electron Transport System
This image depicts one of the many OXPHOS systems embedded in the inner mitochondrial membrane. These are the sites of ATP generation and the utilization of oxygen as the ultimate electron acceptor.
mitochondria Self-replicating membrane-bound cytoplasmic organelles in most eukaryotic cells that complete the breakdown of glucose, producing NADH and ATP (singular term: mitochondrion). The powerhouse of the cell.
Mitochondria and endosymbiosis
During the 1980s, Lynn Margulis proposed the theory of endosymbiosis to explain the origin of mitochondria and chloroplasts from permanent resident prokaryotes.

Mitochondria
Mitochondria have an external membrane and an inner membrane with numerous folds called cristae.
Mitochondrial diseases A set of diseases resulting from mutations in mitochondrial DNA; most prevalent in tissues that depend heavily on oxidative phosphorylation, such as the heart and nervous system.
(4) Mitochondrial - This relatively rare type of genetic disorder is caused by mutations in the nonchromosomal DNA of mitochondria.
How has mitochondrial DNA been used as such?
Mitochondrial DNA has been particularly interesting in regards to reconstructing the history of human populations because mitochondrial DNA is inherited strictly through the mother.
mitochondrial DNA (mtDNA)
Circular or linear DNA of the mitochondria. It codes for only a small but essential part of the mitochondrial proteins and for genes for tRNAs and rRNAs.
Mitochondria
Granular, rod-shaped, or filamentous self-replicating organellae in cytoplasm. Consist of an outer and inner membrane and function in cell respiration and nutrition.
Mitochondria
Surrounded by a double membrane with a series of folds called cristae. Functions in energy production through metabolism. Contains its own DNA, and is believed to have originated as a captured bacterium.
Mitochondria: Mitochondria provide the energy a cell needs to move, divide, produce secretory products, contract - in short, they are the power centers of the cell.
mitochondria - membrane-bounded organelle, about the size of bacterium, that carriesout oxidative phosphorylation and produces most of the ATP in eucaryotic cells.
mitochondria in eucaryotes, a subcellular organelle that conducts cellular respiration
mitochondrion Membrane-bounded organelle that specializes in aerobic respiration (oxidative phosphorylation) and produces most of the ATP in eukaryotic cells.
In bacteria, mitochondria and other ATP-producing organelles, reducing equivalents provided by electron transfer or photosynthesis power this translocation of protons.
Chloroplasts and mitochondria are organelles within eukaryotic cells (cells of organisms other than bacteria, which do not have organelles). These organelles have their own genetic material.
Genome -- all of the genes carried by a single gamete; the DNA content of an individual, which includes all 44 autosomes, 2 sex chromosomes, and the mitochondrial DNA. Genotype -- genetic constitution of an organism.
Mitochondria Mitochondria are the cell's power sources, compartments within the cell that provide its energy. They contain their own DNA, called mitochondrial DNA, a very small amount of DNA inherited only from your mother.
Mitochondrial DNAMitochondria, and chloroplasts in plants, carry their own small chromosomes, usually in multiple copies per organelle. These carry a limited number of genes which code for rRNA, tRNA and a few organelle proteins.
The mitochondria are the most constant type of granule and vary in form from granules to rods and threads. Their function is unknown.
The set of chromosomes in a cell and any other hereditary information found in the mitochondria, chloroplasts, or other locations is collectively known as its genome.
An organism lacking a nuclear membrane and certain organelles such as mitochondria. Refers to both Bacteria and Archae. This term was used synonymously with bacteria before the differences between Bacteria and Archae were understood.
double membrane -- In mitochondria and plastids, there is a two-layered membrane which surrounds the organelle.
Mitochondrion (MITE-oh-KON-dree-un) (plural: mitochondria) The cell's power plant; the organelle that converts energy from food into ATP, fueling the cell.
- The energy molecule of cells, synthesized mainly in mitochondria and chloroplasts. Energy from its breakdown drives many important cellular reactions.
