MITOCHONDRION
By Kyle Munley
MITOCHONDRION PURPOSE
>The Mitochondrion is the site where cellular respiration occurs. Cellular Respiration are
metabolic reactions that take place in cells that convert energy from nutrients into ATP
(Adenosine Triphosphate).
>The Mitochondrion is found in the cytoplasm of nearly all Eukaryotic cells.
>Mitochondria at are the cells power producers in the cytoplasm.
>Mitochondria are also involved in other cell processes such as cell division and growth,
as well as cell death.
MITOCHONDRION CHARACTERISTICS
•
Mitochondria are bounded by a double membrane.
•
Double membranes divide the mitochondrion into two distinct parts: the
intermembrane space and the mitochondrial matrix. The intermembrane space is the
narrowest part between the two membranes while the mitochondrial matrix is the part
enclosed in the innermost membrane.
•
(Cell respiration) The matrix is filled with water and proteins. Those proteins take
food molecules and combine them with oxygen (O 2). The mitochondria are the only
place in the cell where oxygen can be combined with the food molecules. After the
oxygen is added, the material can be digested.
PARTS OF MITOCHONDRION
•
The Mitochondria have several parts such as the cytoplasm, the cytoplasm is where
the energy is turned into ATP.
•
The ribosomes are the protein builders or the protein synthesizers of the cell.
•
DNA is found in the cytoplasm of the mitochondria.
•
The phospholipid bilayer composed of two fatty acids, a glycerol unit, a phosphate
group and a polar molecule and are a major component of cell membranes which
enclose the cytoplasm and other contents of a cell.
•
The inner membrane folds over many times and Is called the cristae.That folding
increases the surface area inside the organelle. Many of the chemical reactions happen
on the inner membrane of the mitochondria.
