Essay On Mitochondria

Mitochondrion is defined as a spherical or rod-shaped organelle that is found within the cytoplasm of the eukaryotic cells, and they are responsible for the production of energy such as ATP, which is needed for cellular processes. Mitochondria is important to eukaryotic cells. They can reduce fatty acids and other lipids, and lengthening chains of fatty acids. The subunits of membrane bound hemeproteins are synthesized and assembled in the mitochondria. Mitochondria is capable of growing or rapidly producing independently within the cell. It has been found that mitochondria contains genetic apparatus for synthesizing enzymes and proteins.

In this essay I will dwell more on the mitochondrion organelle the site for energy production. Elaborating on how the organelle was first established and isolated from cells. Extending to the size, shape, structural organization of the mitochondrion, also the number of these organelles per cell, their location within the cell. Expanding to the functions of the organelle that acts like a digestive system which engulfs nutrients and break them down to create energy for the cells for metabolism, the process of energy creation is known as the cellular respiration.

DISCOVERY OF MITOCHONDRIA

Mitochondria was observed about 100 years ago by the Swiss anatomist Albert Von Kollicker who teased these organelles and studied their osmotic behavior in different salt solutions. In 1890’s Richard Altmann established them and called them the “bioblasts”. The Carl Benda coined the term mitochondrion which has its origin in Greek language which meant thread-like granules and which they saw under the light microscope. In 1900 Michaela introduced the use of the Janus green B to stain the mitochondr...

...cells that require high energy such as the muscle cells. It contains two functionally different membranes which is the inner and the outer membrane. And in between the membranes there is a fluid, the inner membrane protects the matrix of the cell. Mitochondria is a multifunctional organelle, it plays different roles with different cells.
