In cell biology, a mitochondrion (plural mitochondria) is a membrane-enclosed organelle found in most eukaryotic cells.[1] These organelles range from 0.5 to 10 micrometers (μm) in diameter. Mitochondria are sometimes described as "cellular power plants" because they generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of the chemical energy.[2] In addition to supplying cellular energy, mitochondria are involved in a range of other processes, such as signaling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth.[3] Mitochondria have been implicated inseveral human diseases, including mitochondrial disorders[4] and cardiac dysfunction,[5] and may play a role in the aging process. The word mitocho ndrion comes from the Greek μίτος or mitos, thread + χονδÏίον or chondrion, granule . Several characteristics make mitochondria unique. The number of mitochondria in a cell varies widely by organismand tissue type. Many cells have only a single mitochondrion, whereas others can contain several thousand mitochondria.[6][7] The organelle is composed of compartments that carry out specialized functions. These compartments or regions include the outer membrane, the , the inner membrane, and thecristae and matrix. Mitochondrial proteins vary depending on the tissue and the species. In humans, 615 distinct types of proteins have been identified fromcardiac mitochondria;[8] whereas in Murinae(rats), 940 proteins encoded by distinct genes have been reported.[9] The mitochondrial proteome is thought to be dynamically regulated.[10] Although most of a cell's DNA is contained in the cell nucleus, the mitochondrion has its own independent genome. Further, its DNA shows substantial similarity to bacterial genomes.

Example of chromatin?
the DNA in a bacterium is about 100 times as long as the bacterium itself. it must therefore be very tightly folded
An unknown gas is found to diffuse through a porous membrane 2.92 times more slowly than rm H 2.?
17.2 amu
What organelles do the bacteria cell and the plant cell have in common?
Cell walls: Plants have cellular walls made mainly of cellulose (a large carbohydrate); bacteria have cell walls made mainly of peptidoglycan (a protein).Ribosomes: Plants, animals, and bacteria all have ribosomes but those of bacteria (prokaryotes) differ in structure to those plants and animals (eukaryotes).Bacteria do not have any true (membrane-bound) organelles, but some, such as cyanobacteria, have the ability to photosynthesize (make their own food from sunlight). They do this with their outer membrane which is folded inward many times to create compartment-like areas and membrane surface area for chemical reactions to take place. (Photosynthesis requires many different proteins that pass through a membrane.)Endosymbiosis: It is thought that the chloroplast in all plants began as a species of cyanobacteria that became engulfed by early plant ancestors; instead of being broken down, the bacteria benefited the host cells by making food. In return the host cell provided a comfortable home.
What process is when molecules pass through the cell membrane using special proteins?
In many instances,that is active transportation.But some times they are involved in facilitaed diffusion.
How many times does the nucleus divide during meiosis?
To be more accurate the nucleus doesn't split in mitosis because after DNA replicates in interphase and prophase starts nuclear membrane is removed and there is no longer a nucleus just free chromosomes. These separate in anaphase and then in telophase where two daughter cells are going to be produced the nuclear membrane reforms as well as the nucleolus forming two cells with identical nuclei.
What feature of the inner membrane of the mitochondrion allow the organelle to produce a great amount of energy?
The inner membrane is folded on itself multiple times in structures called "christae". These folds dramatically increase the surface area within the mitochondrion, which increases how much energy the organelle can make.

Can paper be folded in half more than 7 times?
A standard piece of paper cannot be folded 7 times, but the Mythbusters folded a hangar sized piece of paper 11 times.
What is the structure of a mitochondrion?
The mitochondria is the powerhouse of the cell. It has two membranes. The outer membrane covers the organelle and contains it. The inner membrane folds over many times. This folding increases the surface are inside the organelle.
How many times can an a4 piece of paper be folded in half?
Any paper can be folded in half for 6 times.
How many times have you folded a piece of paper?
the rules of matter will only allow it to be folded 7 times max
What is the purpose of the inner mitochondrial membranes being five times the area of the outer mitochondrial membranes and 17 times that of the cells plasma membrane?
It increases the surface for oxidative phosphorylation
What is the formula to determine how many sides when a piece of paper is folded in half repeatedly?
If by sides you refer to the number of paper slices you can hold then the formula is this: assuming that when the paper has not been folded, the number of times folded is equal zero then the equation is: 2x, where x is the number of times folded. for example if the paper has been folded four times the number of sides is: 24 = 16
How many times can a piece of a4 paper be folded in half?
Any size sheet of paper can only be folded in half 7 times.
How many times was a quarto folded?
Four.
