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 is the function of the mitochondria simple answer?
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 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 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 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 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.
What does mitochondria do in cellular respiration?
Mitochondria are double membrane bound cytoplasmic organelles present in most eukaryotic cells. They are responsible for aerobic respiration, producing energy for the cell, which they achieve through oxidative phosphorylation.
What are the functions of mitochondria Class 9?
1)They are sites of cellular respiration. 2)They uses oxygen to oxidise carbohydrates and fats present in the cell to carbon dioxide and water. Oxidation releases energy,a portion of which is used to form ATP. Since mitochondria synthesises energy rich compound ATP it is called powerhouse of cell.
What is the importance of mitochondria in our environment?
Mitochondria generate energy for cells to carry out activities. This energy is in the form of adenosine triphosphate (ATP). They also take part in cell signalling and help cells sense and adapt to their environment.
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 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 the role of mitochondria in making energy?
Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. ... NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP). In ATP the energy is stored in the form of chemical bonds.
What is the function of mitochondria in Class 11?
Mitochondria are the sites of aerobic respiration and produce cellular energy in the form of ATP, hence they are called 'power houses' of the cell. The matrix also possesses single circular DNA molecule, a few RNA molecules, ribosomes, and a few components of protein synthesis.
What are the function of mitochondria and and class of?
Mitochondria are called the powerhouse of the cell, as these cell organelles are responsible for producing ATP molecules, the energy currency of the cell. Other important functions of mitochondria are: ... Mitochondria are also involved in several biochemical reactions associated with cellular respiration.
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).
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.
