Mitochondria

    Self-replicating membrane-bound cytoplasmic organelles in most eukaryotic cells that complete the breakdown of glucose. Singular: mitochondrium.

RELATED TERMS
--------------------------------------

Eukaryotic
The living world is divided into two classes of organism. Eukaryotic and, much simpler, prokaryotic organisms such as bacteria. Generally eukaryotes are diploid and their cells have internal organelles, such as nuclei. Prokaryotes are haploid with much simpler cells.

Glucose
The only simple carbohydrate that circulates in the bloodstream. Glucose is the primary fuel used by the brain. It can also be stored in the liver and muscles in a polymer form known as glycogen.

Mitochondrium
Self-replicating membrane-bound cytoplasmic organelles in most eukaryotic cells that complete the breakdown of glucose. Plural: mitochondria.



SIMILAR TERMS
--------------------------------------

Mito doctors
All doctors near Mito, Japan. Doctors who can assist a patient in Mito.

Mitochondrial heteroplasmy
An atypical condition characterized by the presence of more than one type of mitochondrial DNA in a single individual. Normally, each individual has only one type of mitochondrial DNA, inherited from his or her mother through the egg at fertilization. (Mitochondria from the sperm are systematically eliminated by the egg at fertilization.)Cloned organisms may exhibit mitochondrial heteroplasmy (having a mixture of mitochondria from both the donor cell and the recipient egg) because this elimination system may be bypassed during the cloning process.

Mitochondrion
Plural: mitochondria. A cellular structure in the cytoplasm that provides energy to the cell. Each cell contains many mitochondria. In humans, a single mitochondrion contains 37 genes on a circular mitochondrial DNA, compared with about 35,000 genes contained in the nuclear DNA.

Mitochondrium
Self-replicating membrane-bound cytoplasmic organelles in most eukaryotic cells that complete the breakdown of glucose. Plural: mitochondria.

Mitogen
A substance that stimulates the proliferation of many different clones of lymphocytes.

Mitomycin
Mitomycin is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): mitomycin.

Mitosis
The division of the cell's nucleus and nuclear material of a cell; consists of four stages: prophase, metaphase, anaphase, and telophase. Mitosis occurs only in eukaryotes. The DNA of the cell is replicated during interphase of the cell cycle and then segregated during the four phases of mitosis.

Mitoxantrone
Mitoxantrone is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): mitoxantrone.

Metacarpals
Five long bones of the hand, running from the wrist to the fingers.

Metacarpus
The metacarpus is the intermediate part of the hand skeleton that is located between the fingers distally and the carpus which forms the connection to the forearm. It consists of five cylindrical bones which are numbered from the radial to the ulnar side (ossa metacarpalia I-V); each consists of a body and two extremities.

Meiosis
A type of cell division in which 4 daughter cells are produced, each having half the chromosome number of the parent cell; in plants, meiosis occurs in the sporangia on the sporophyte, and produces tetrads of haploid spores from the diploid spore mother cells; these spores typically grow into gametophytes; haploid cells cannot go through meiosis, since the haploid number of chromosomes is the minimum number a cell requires to survive.

Mitosis
The division of the cell's nucleus and nuclear material of a cell; consists of four stages: prophase, metaphase, anaphase, and telophase. Mitosis occurs only in eukaryotes. The DNA of the cell is replicated during interphase of the cell cycle and then segregated during the four phases of mitosis.

Metaphase
The stage of eukaryotic cell division (mitosis or meiosis) in which the chromosomes line up at the equator of the cell.

MRI
Magnetic Resonance Imaging is a diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body.

Metabolism
The chemical activity that occurs in cells, releasing energy from nutrients, or using energy to create other substances, such as proteins.

Macrolide
A group of drugs (typically antibiotics) whose activity stems from the presence of a macrolide ring, a large lactone ring to which one or more deoxy sugars, usually cladinose and desosamine, are attached. The lactone ring can be either 14, 15 or 16-membered. Macrolides belong to the polyketide class of natural products.
