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 does the mitochondria do and why is it important?
Mitochondria are often referred to as the powerhouses of the cell. They help turn the energy we take from food into energy that the cell can use. But, there is more to mitochondria than energy production. ... They generate the majority of our adenosine triphosphate (ATP), the energy currency of the cell.
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.
Why does the heart have high mitochondria?
The heart is the most metabolically active organ in the body and highly depends on oxidative energy generation in mitochondria to supply the large amount of adenosine triphosphate (ATP) required for its continuous contractile activity.
What is a mitochondrion and what function does it serve in the cell is it found in plant cells animal cells or both?
Today, mitochondria are found in fungi, plants, and animals, and they use oxygen to produce energy in the form of ATP molecules, which cells then employ to drive many processes.
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.
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.
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).
Why is the mitochondria important for staying alive?
Known as the “powerhouse of the cell” they are primarily responsible for converting the air we breathe and the food we eat into energy that our cells can use to grow, divide and function. ... Mitochondria produce energy by turning glucose and oxygen into a chemical called ATP.
What would happen without 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. ...
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 do mitochondria move around the cell?
Mitochondria primarily move by the action of molecular motors along cytoskeletal elements (Figure 2 and Table 1). Like other organelles, mitochondria associate with specific motor isoforms through organelle-specific adaptors, and their movement is sensitive to disruption of these motors and adaptor proteins.
