Definitions &Translations U.S. National Library of Medicine (5.00 / 1 vote) Rate this definition: Mitochondria. Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae.

What Are Mitochondria? View full size image. Mitochondria are specialized structures unique to the cells of animals, plants and fungi. They serve as batteries, powering various functions of the cell and the organism as a whole. Though mitochondria are an integral part of the cell, evidence shows that they evolved from primitive bacteria.itochondria are unlike most organelles (with an exception of plant chloroplasts) in that they have their own set of DNA and genes that encode proteins. Plant mitochondria were first observed by Friedrich Meves in 1904, as mentioned by Ernster and Schatz (Journal of Cell Biology, 1981).

This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.Cells that need a lot of energy, like muscle cells, can contain thousands of mitochondria.t is for this reason that mitochondria are often referred to as the powerhouses of the cell.

- The mitochondrion (plural mitochondria) is a double membrane-bound organelle found in most eukaryotic cells. The word mitochondrion comes from the Greek μίτος, mitos, i.e. thread, and χονδρίον, chondrion, i.e. granule or grain-like.Mitochondria range from 0.5 to 1.0 μm in diameter. A considerable variation can be seen in the structure and size of this organelle. Unless specifically stained, they are not visible.he matrix is the space enclosed by the inner membrane. It contains about 2/3 of the total protein in a mitochondrion. The matrix is important in the production of ATP with the aid of the ATP synthase contained in the inner membrane.

The energy in the bonds of these compounds (glucose) can later be released during the process of cellular respiration.

Enzyme Allosteric sites are pockets on the enzyme, distinct from the active site, that bind to molecules in the cellular environment. These molecules then cause a change in the conformation or dynamics of the enzyme that is transduced to the active site and thus affects the reaction rate of the enzyme.

- Mitochondria is known as powerhouse of cell because the major part of cellular respiration occurs in it, thereby maximum amount of ATP is generated there. This ATP is the energy provider to all the major/minor vital biological functions. ATP is called the energy/power currency of the cell.

- New Mitochondria means more potential energy. This is revolutionary for you and your cells, especially in areas like your heart and brain where we can find the highest concentration of mitochondria in your body! Protect Antioxidant: Antioxidants are the buzz now a days because they protect you from damage on the cellular level.

CONTENTS Mitochondria - Turning on the Powerhouse. Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration. Many of the reactions involved in cellular respiration happen in the mitochondria. Mitochondria are the working organelles that keep the cell full of energy. Mitochondria are small organelles floating free throughout the cell.

Whats the difference between mitchondria and ribosomes? Best Answer: Mitochondria are sometimes described as cellular power plants, because they generate most of the cell's supply of ATP, used as a source of chemical energy. The number of mitochondria in a cell varies widely by organism and tissue type.lthough most of a cell's DNA is contained in the cell nucleus, mitochondria have their own independent genomes. According to the endosymbiotic theory, mitochondria are descended from free-living prokaryotes.

What are Mitochondria? What are mitochondria and what do they do? The “powerhouses of the cell”, that’s how many people know mitochondria. The parts of cells that turn sugars, fats and proteins that we eat, into forms of chemical energy that the body can use to carry on living. Every living thing is made of cells: tiny compartments contained by a membrane.

Mitochondria and Chloroplast Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP).he mitochondrion is different from most other organelles because it has its own circular DNA (similar to the DNA of prokaryotes) and reproduces independently of the cell in which it is found; an apparent case of endosymbiosis.

Mitochondria What they mean is that mitochondria get the energy out of glucose in respiration: they use this energy to make a wonderful chemical called ATP. Cells need energy for other processes such as the synthesis of proteins from amino-acids and the replication of DNA.

Cell Biology/Organelles/Mitochondria Mitochondria (singular mitochondrion) are the 'electric generators' of cells. They take oxygen and produce carbon dioxide together with ATP, the fuel of most of the activities of the cell. Because they take oxygen and release CO2, it is easy to think they 'breathe'.

Mitochondrial DNA Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA. This genetic material is known as mitochondrial DNA or mtDNA.

What is mitochondria? What does it do? Best Answer: Mitochondria are often called the powerhouse of the cell because they produce ATP from sugar and other organic molecules.The name means thread bodies about the same size as a bacterium. They have two membranes with the inner membrane folded to form partial partitions in the cavity.n cell biology, a mitochondrion (plural mitochondria) is a membrane-enclosed organelle found in most eukaryotic cells.These organelles range from 1–10 micrometers (μm) in size.

Function of Mitochondria The main function of mitochondria is the production of energy during the production of adenosine triphosphate (ATP) via the TCA Cycle (which is also as the Krebs Cycle and the Citric Acid Cycle). That process is an important metabolic pathway (see also what is metabolism).

Mitochondria Mitochondria are well-defined cytoplasmic organelles of the cell which take part in a variety of cellular metabolic functions. Survival of the cells requires energy to perform different functions.The mitochondria are important as the fact that these organelles supply all the necessary biological energy of the cell, and they obtain this energy by oxidizing the substrates of the Krebs cycle.itochondria is a membrane bound cellular structure and is found in most of the eukaryotic cells. The mitochondria ranges from 0.5 to 1.0 micrometer in diameter. The mitochondria are sometimes described as power plants of the cells.
