Mitochondria
Mitochondria are eukariyotic cell organells.It is the site of aerobic respiration which generates energy stored in ATP's.They are also known as the power houses of the cell.
583 Questions
What is the interior compartment of the mitochondria?
The interior compartment of the mitochondria is called the matrix. It contains enzymes involved in the citric acid cycle, fatty acid oxidation, and mitochondrial DNA replication. The matrix is where many metabolic reactions take place to generate energy in the form of ATP.
What is mitochondria compared to?
Mitochondria are often described as the powerhouse of the cell, as they are responsible for generating most of the cell's supply of adenosine triphosphate (ATP), which is used as a source of energy. They are unique organelles that have their own genetic material and replicate independently within the cell.
Chloroplasts and mitochondria are?
Chloroplasts are organelles found in plant cells that carry out photosynthesis, converting sunlight into energy. Mitochondria are organelles found in animal and plant cells that produce energy through cellular respiration. Both organelles have their own DNA and are thought to have originated as free-living prokaryotic organisms that were engulfed by ancestral eukaryotic cells.
What would happen to a eukaryotic cell if it's mitochondria was destroyed?
It will not get energy. Functions of cells would be stopped
What did Dr. Lynn Margulis suggest about mitochondria and chloroplasts?
They were cells before and then they came together with a cell and then they became mutually dependent.
What part of the sperm cell contains mitochondria that supplies energy to the flagella?
Mitochondria are in mid part of sperm.They gives energy to swim.
What is the basic function of mitochondria?
It is the power house of the cell.It generates ATP through respiration.
Does epithelium cell have mitochondria?
So that lots of ATP can be produced, which can then release energy for active transport. Remember that epithelial cell are cells that release substances and can take substances in (exocytosis and endocytosis). This requires energy, so there are therefore lots of mitochondria.
What is the purpose of the folds in mitochondria inner sac?
It is to carry out electron transport chain. The last step of respiration
There are three characteristics of mitochondria and chloroplasts that support this theory. First, both mitochondria and chloroplasts have two membranes surrounding them. Second, like prokaryotes, mitochondria and chloroplasts contain ribosomes, as well as a circular DNA molecules attached to their inner membranes. Third, mitochondria and chloroplasts are autonomous.
How do prokaryotes get their ATP without mitochondria?
the stroma, consisting of set of flat disc like sacs called thylakoid. The thylakoid membrane encloses a fluid filled lumen or space, which is separated by thylakoid membrane with stroma. The chlorophyll is embedded in the thylakoid membrane. Chlorophyll absorbs light and converts it into chemical energy of ATP and NADPH; the products which synthesize carbohydrate in the stroma of chloroplast.
But photosynthetic prokaryotes lack chloroplast all together in their cells. So, for carbohydrate synthesizing, they do have unstacked photosynthetic membranes, which work like thylakoid.
Which parent does the mitochondria come from?
Mitochondria is inherited by mother. Every one comes from mother
What chloroplast and mitochondria contain their own genetic information in form of?
Both chloroplasts and mitochondria have their own sets of chromosomes composed of DNA.
What process does mitochondria take part in?
They are responsible for respiration . They are generating power
What is the singular term for mitochondria?
Mitochondria is already plural. The singular form is Mitochondrion.
Mitochondria IS plural. The single form is mitochondrion.
Why is there no mitochondria found in the bacteria cell?
Bacteria are prokaryotic organisms.Prokaryotes do not have mitochondria.
How does the mitochondria help the sperm cell move?

A sperm cell, or spermatozoon, is the haploid cell that is the male gamete. It is carried in fluid called semen, and is capable of fertilising an egg cell to form a zygote. A zygote can grow into a new organism, such as a human. Sperm cells contain half of the genetic information needed to create life. Generally, the sex of the offspring is determined by the sperm with the chromosomal pairs "XX" and "XY". Sperm cells were first observed by Antoni van LeeuwenhoekAnton van Leeuwenhoek ( October 24, 1632 August 26, 1723) was a tradesman and scientist from Delft, in the Netherlands. He is best known for his contribution to improvement of the microscope and his contributions towards the establishment of cell biology. in 1679Events January 24 King Charles II of England disbands Parliament August 7 The brigantine Le Griffon which was commissioned by Rene Robert Cavelier, Sieur de La Salle, is towed to the southern end of the Niagara River, to become the first ship to sail the.
1 Sperm structure and sizeIndividual spermatozoa are highly differentiated cells, composed normally of a head, basal body (or midpiece), and tail. The head contains some cytoplasmCytoplasm is the viscid, semifluid matter contained within the plasma membrane of a cell that helps to hold the cell together. In contrast to the protoplasm, however, the cytoplasm does not include the cell nucleus. The watery or aqueous component of the and the nuclear material for fertilization. The basal bodyA basal body is a short cylindrical array of microtubules plus their associated proteins found at the base of a eukaryotic cell cilium or flagellum. Serves as a nucleation site for the growth of the axoneme. Closely similar in structure to a centriole. contains a large concentration of mitochondria that provide the energy for sperm motility through the production of ATP. The spermatozoan tail is typically a flagellum used for propulsion.
In humans, sperm cells consists of a head 5 µm by 3 µm and a tail 50 µm long. The tail flagellates, which propels the sperm cell. The cell is characterized by a minimum of cytoplasm.
2 Sperm productionMain article: Spermatogenesis
Sperm are produced in the seminiferous tubule s of the testes in a process called spermatogenesis. Round cells called spermatogonia divide and differentiate eventually to become sperm. During sexual intercourse the sperm is deposited in the vagina - and then it moves to the ovum.

Are mitochondria n found in a prokaryotes cell?
No,they cannot be found.They are only found in eukariyotic cells
Why mitochondria have folded inner membranes?
Foldings increases surface area.So respiration can be done efficiently.
What happens to mitochondria during exercise?
When we exercise energy is needed to perform processes such as muscle contraction and nerve transmission. This energy comes in the form of the molecule adenosine triphosphate (ATP). In the cell, aerobic respiration converts glucose and oxygen into carbon dioxide and water to produce ATP. This occurs in many stages to gradually release this ATP energy from the glucose. When oxygen is unavailable or insufficient, such as during vigorous excerise, some ATP can be obtained from anaerobic respiration. This allows for a quick burst of energy such as when sprinting but produces the waste product lactic acid which causes muscle fatigue as it builds up. After exercise the lactic acid can be broken down with more oxygen.
Why do you think that muscle cells have many mitochondria?
Any cell that is going to require large amounts of energy in a short period of time will tend to have a high number of Mitochondria. This is because mitochondria produces the energy currency of the cell, adenosine triphosphate, which produces energy.
What is mitochondria involved in?
mitochondria is involved in generation of energy for the cell in the form of ATP so that it may carry out the life processes
How do you mitochondria in a sentence?
mitochondria have an inner and outer membrane.theinne membranehas many twists and folds(called cristae),which increase the surface area available to proteins.
