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 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 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 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.
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.
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 the mitochondria is missing?
When mitochondria cannot convert food and oxygen into life-sustaining energy, cell injury and even cell death follow. When this process is repeated throughout the body, organ systems begin to fail and even stop functioning.
How does the mitochondria keep us alive?
Mitochondria are critical to cell survival in a variety of ways. For instance, they store calcium ions, helping cells maintain the right concentration of these electrically charged particles involved in blood clotting, muscle contraction and other important tasks.
What is a mitochondrion and what function does it serve in the cell is it found in plant cells animal cells or both?
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.
What role do mitochondria play in metabolism?
Mitochondria, the cell's powerhouses, produce up to 95% of a eukaryotic cell's energy (ATP) through oxidative phosphorylation to fuel cellular activity. They are also highly dynamic organelles that constantly remodel and turn over.
How are mitochondria adapted to their function?
Mitochondria have a double membrane structure, with an inner layer with many folds to create a high surface area. This provides more space for more metabolising proteins and therefor they are able to create more energy at one time.
What is the advantage to cells of having mitochondria?
Mitochondria are advantageous as they allow the cell to respire aerobically, without them they can only respire anaerobically. As a result of this aerobic respiration due to the mitochondria's presence they can produce more ATP.
How does the mitochondria make 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.
Why is the mitochondria the most important organelle?
As the power plants in virtually every human cell (as well as animal, plant, and fungi cells), mitochondria play an essential role in creating energy to drive cellular function and basically all of our biological processes.
How does mitochondria produce energy for the cell answer key?
Mitochondria are the powerhouses of the cell because they "burn" or break the chemical bonds of glucose to release energy to do work in a cell. ... This releases energy (ATP) for the cell. The more active a cell (such as a muscle cell), the more mitochondria it will have.
Can a cell survive without mitochondria?
You can't survive without mitochondria, the organelles that power most human cells. ... Mitochondria are the descendants of bacteria that settled down inside primordial eukaryotic cells, eventually becoming the power plants for their new hosts.
What causes mitochondrial damage?
On a physiological level, mitochondrial dysfunction is caused by exposure to certain environmental factors (such as certain pharmaceutical drugs, occupational chemicals and cigarette smoke) or genetic abnormalities (of both mitochondrial and nuclear DNA).
What is bad about the mitochondria?
When the mitochondria are defective, the cells do not have enough energy. The unused oxygen and fuel molecules build up in the cells and cause damage. The symptoms of mitochondrial disease can vary.
