what is the function of mitochondria
Answers
Answer:
Mitochondria (singular: mitochondrion) are double membrane-bound cell organelles with a typical size of 0.75-3 μm². They are found in most mammalian cells, with notable exceptions including mature erythrocytes. Classically referred to as the ‘powerhouse of the cell’, they are the site of the majority of ATP synthesis and are therefore exceptionally important to function both microscopically and macroscopically.
In this article we will look at the structure and function of mitochrondria, and consider some clinical relevance.
The mitochondrion is the site of ATP synthesis for the cell. The number of mitochondria found in a cell are therefore a good indicator of the cell’s rate of metabolic activity; cells which are very metabolically active, such as hepatocytes, will have many mitochondria.
Mitochondria also have a role to help maintain the intracellular environment. They:
Store caspases responsible for triggering apoptosis.
Are able to transiently store calcium contributing to calcium homeostasis.
In brown adipose tissue mitochondria have an alternative function of heat production using the electron transport chain.

Answer:
Mitochondria are a part of eukaryotic cells. The main job of mitochondria is to perform cellular respiration. This means it takes in nutrients from the cell, breaks it down, and turns it into energy. This energy is then in turn used by the cell to carry out various functions.It also stores ATP which is energy currency of the cell.
