Mitochondria are small organelles in the cells of plants and animals that create energy by converting food into useful chemical products. The mitochondrion is a flattened, circular structure about 10 micrometers wide. It has a small outer mitochondrial membrane and an inner cell membrane. There are two copies of the mitochondrial DNA, one in each nucleus.

How are mitochondria created?
Mitochondria are created early in embryogenesis when the cells undergo fusion of two similar types of cells. The inner mitochondrial membrane is then built up by copying and pasting individual sections from other parts of the cell.
Where are mitochondria produced?
Mitochondria are produced in cells of the lepidopteran family.
Can we make artificial mitochondria?
There is no currently existing method to create artificial mitochondria, and the technology does not yet exist.
Do mitochondria produce themselves?
There is no definitive answer to this question as it remains unclear how mitochondria originate and whether or not they are self-producing. Some researchers hypothesize that mitochondria may have emerged from bacterial cells, while others speculate that they may be generated from the genetic material inside of apoptotic cells. Regardless of their origin, it is clear that mitochondrial function relies on a close partnership between the organelles and the cell nucleus.
Did mitochondria come from bacteria?
No, mitochondria did not come from bacteria. Mitochondria are organelles in cells that produce energy by converting organic matter into ATP. They were initially discovered in yeast cells and were originally thought to be endosymbionts, or symbiotic organisms that originated from another cell. However, it is now clear that they formed independently and evolved after the early eukaryotic cells diverged from prokaryotes.
How do mitochondria evolve from bacteria?
Mitochondria evolved from bacteria through a process called endosymbiosis. In this process, one type of bacterium engulfed another type of bacterium and took over its metabolic processes. The mitochondria in the cells of these bacterial hosts were able to convert energy from food into cellular ATP. This relationship allowed the mitochondria to proliferate independently and eventually take on their own evolutionary path.
How is a new mitochondria formed by the pre existing ones?
The pre-existing mitochondria fuse with other cells in the body to create a new mitochondria.
How is ATP made?
ATP is made from ADP and Pi by the enzyme ATP synthase, which uses energy from glucose in the cell to make a phosphate molecule.
Do all humans have the same mitochondrial DNA?
Scientists recently discovered that some people have mitochondrial DNA that is different from the rest of their DNA. This means that there are a small number of people who do not share the same mitochondrial DNA as all other humans.
How do mitochondria obtain energy?
Mitochondria use fat, carbohydrates, and protein to obtain energy.
What is mitochondrial DNA transfer?
Mitochondrial DNA transfer is when a pregnant woman transfers mitochondrial DNA to her baby from her eggs or sperm. This can happen during intercourse, before conception, or outside of pregnancy.
What is in a mitochondria?
Mitochondria are organelles within cells that use energy from food to perform essential metabolic tasks. Mitochondria produce ATP, the molecule responsible for cellular energy production.
How are human mitochondria inherited?
Mitochondria are inherited in a manner that is not fully understood. Scientists think that mitochondria may be passed down from the mother in some way, although this has yet to be confirmed.
Where do mitochondria in the zygote come from?
Mitochondria in the zygote come from the sperm and egg.
Do virus have mitochondria?
Mitochondria are organelles in the cell that produce energy for cells. Viruses do not have mitochondria, so it is unclear whether they can produce energy.
Are mitochondria parasites?
There is no single answer to this question as it depends on the definition of “parasite” that is used. Some scientists may see mitochondria as parasites because they require host cells in order to function, while others may consider them symbionts, since they share some biological benefits with their hosts. Overall, it is difficult to make a definitive statement about whether or not mitochondria are parasites based on the current literature.
Is there DNA in mitochondria?
There is no DNA in mitochondria. Mitochondria are organelles within cells that use energy from food to create ATP, which the cell can then use to carry out its chemical reactions.
Did mitochondria evolve once?
There is no one answer to this question because it depends on a number of factors, including the definition of “mitochondria.” Some people might say that mitochondria evolved once because they are specialist cells that burn energy in the body. Other scientists might say that mitochondrial evolution is ongoing and occurs as mutations within the cells’ DNA.
Why did mitochondria come before chloroplasts?
The first cells were likely algae, and mitochondria are similar to organelles in plant cells. Chloroplasts evolved from a photosystem that piggybacked on the mitochondrial ancestor of today’s plants.
Can mitochondria survive on its own?
A mitochondrial carrier can survive on its own if the cell dies. Mitochondria are able to remove damaged organelles and proteins and resequence the DNA to create new mitochondria.
What does a chloroplast contain?
A chloroplast contains photosynthesis proteins and chiral protein complexes.
What are the three ways ATP is generated?
ATP is generated through the process of respiration. Respiration is the process by which an organism uses energy to produce ATP from glucose. First, the cell harnesses solar energy to split glucose into high-energy form, called Redmond glycogen and low-energy waste products like water and carbon dioxide. Then enzymes combine these small molecules together to create two new forms of energy: adenosine triphosphate (ATP) and hydrogen ions. The first electron from hydrogen ions splits off a phosphate group from ATP, creating another molecule of adenosine triphosphate (ADP). The second electron liberates more hydrogen ions, similar to how batteries work in your car.
How is ATP converted into energy?
ATP is converted into energy in the body by a process called organic chemistry. There are three steps to this process: breaking down glucose, using oxygen to make energy, and converting that energy into ATP.
How is ATP made from glucose?
ATP is made from glucose through a process called chemiosmosis. In chemiosmosis, glucose is converted into ATP in the cell’s mitochondria and then released into the cell.
