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).

What function do mitochondria have?
Known as the “powerhouses of the cell,” mitochondria produce the energy necessary for the cell's survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.
What does the mitochondria do simple answer?
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. ... Many of the reactions involved in cellular respiration happen in the mitochondria.
What are 3 things that mitochondria do?
In addition to producing energy, mitochondria perform some other functions for the cell including cellular metabolism, the citric acid cycle, producing heat, controlling the concentration of calcium, and producing certain steroids. They can quickly change shape and move around the cell when needed.
What are two functions of mitochondria?
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. Mitochondria are also involved in other tasks, such as signaling between cells and cell death, otherwise known as apoptosis.
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 happens if there is no mitochondria?
Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. ...
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.
Do mitochondria have DNA?
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. ... Mitochondrial DNA contains 37 genes, all of which are essential for normal mitochondrial function.
What is unique about mitochondria?
Mitochondria play a critical role in the generation of metabolic energy in eukaryotic cells. In addition, mitochondria are unique among the cytoplasmic organelles already discussed in that they contain their own DNA, which encodes tRNAs, rRNAs, and some mitochondrial proteins. ...
What is the most important thing about mitochondria?
Mitochondria function as batteries that produce more than 90% of the energy in your body's cells. Mitochondria are really important in high-energy demanding organs such as your heart, liver, muscles and brain. 40% of each heart muscle cell and 25% of each liver cell are made up of mitochondria.
Which organs have 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!
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.
How do mitochondria produce ATP?
Most of the adenosine triphosphate (ATP) synthesized during glucose metabolism is produced in the mitochondria through oxidative phosphorylation. This is a complex reaction powered by the proton gradient across the mitochondrial inner membrane, which is generated by mitochondrial respiration.
How do you get ATP?
It is the creation of ATP from ADP using energy from sunlight, and occurs during photosynthesis. ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not.
Why mitochondria is the powerhouse of the cell?
Mitochondria are often called the “powerhouses” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP), the cell's main energy-carrying molecule. ... Cellular respiration is the process of making ATP using the chemical energy found in glucose and other nutrients.
