What is mitochondria in simple words?
Mitochondria (sing. mitochondrion) are organelles, or parts of a eukaryote cell. They are in the cytoplasm, not the nucleus. They make most of the cell's supply of adenosine triphosphate (ATP), a molecule that cells use as a source of energy. ... This means mitochondria are known as "the powerhouse of the cell".
What is mitochondria and its function?
Mitochondria. Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Where is a mitochondria?
Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Each cell contains hundreds to thousands of mitochondria, which are located in the fluid that surrounds the nucleus (the cytoplasm).
What is the best definition of mitochondria?
Definition of mitochondrion
: any of various round or long cellular organelles of most eukaryotes that are found outside the nucleus, produce energy for the cell through cellular respiration, and are rich in fats, proteins, and enzymes — see cell illustration.
What part of the human body has the most mitochondria?
A. Your heart muscle cells – with about 5,000 mitochondria per cell. These cells need more energy, so they contain more mitochondria than any other organ in the body!
Why do we need mitochondria?
They help turn the energy we take from food into energy that the cell can use. ... Present in nearly all types of human cell, mitochondria are vital to our survival. They generate the majority of our adenosine triphosphate (ATP), the energy currency of the cell.
What is mitochondrial metabolism?
Mitochondrial metabolism encompasses pathways that generate ATP to drive intracellular unfavorable energetic reactions and produce the building blocks necessary for macromolecule synthesis. ... To date, much of our understanding of the concentration of mitochondrial metabolites has been limited to in vitro settings (2).
How long do mitochondria live in humans?
about 2 billion mitochondria are made every second throughout a person's life. the lifespan of a mitochondrion averages around 100 days.
Who has mitochondrial DNA?
Mitochondrial DNA is the small circular chromosome found inside mitochondria. The mitochondria are organelles found in cells that are the sites of energy production. The mitochondria, and thus mitochondrial DNA, are passed from mother to offspring.
Do mitochondria have RNA?
In human mitochondria, RNA is produced from a very compact, circular double stranded genome that encodes two ribosomal RNAs (mt-rRNA), 22 mt-tRNAs and 13 proteins. ... The rest of the mitochondrial proteome, including factors involved in mt-RNA metabolism, is encoded by the nucleus and must be imported into the organelle.
Are mitochondria bacteria?
The endosymbiotic hypothesis for the origin of mitochondria (and chloroplasts) suggests that mitochondria are descended from specialized bacteria (probably purple nonsulfur bacteria) that somehow survived endocytosis by another species of prokaryote or some other cell type, and became incorporated into the cytoplasm.
What is mitochondria explained to kids?
You can think of the mitochondria as the energy factory or power plant of the cell. Mitochondria produce energy through the process of cellular respiration. The mitochondria take food molecules in the form of carbohydrates and combine them with oxygen to produce the ATP.
How do mitochondria make energy?
Mitochondria are organelles – 'small organs' within each cell. They produce energy in the form of a molecule called ATP (adenosine triphosphate) which gets used throughout the cell to power the different jobs it has to do. ... As they do so, energy is extracted and transferred into ATP.
What are mitochondria Class 9?
Mitochondria are round "tube-like" organelles that provide energy to a cell in the form of ATP (Adenosine Triphosphate) for performing different chemical activities for the sustainance of life.
