Mitochondria are double-membraned organelles. The mitochondria is know as “energy currency of the cell” or “the power house of the cell” because it produces ATP. ATP stands for adenosine triphosphate, it is a type of energy that is released. They contain their own own ribosomes and dna. It helps in cellular respiration because of production of ATP in this cell. ATP is produced by consuming glucose and other nutrients.

Mitochondria uses oxygen and as a by product it releases carbon dioxide. In fact after every breath a human inhales oxygen and the carbon dioxide which is released out of the body is by the product of the cell. One human can have one single large mitochondria or even thousands of small mitochondria. It also stores calcium as it a very important part of our body it helps in the functioning of our muscles fertilisation, blood Clotting etc. Size of one mitochondria is generally 1-10 micrometers in length.

ATP is also a very good source of energy for our body. they have a power to recycle them. It is produced it plants, animals and humans. It can be used in Endothermic and exothermic processes. When a cell in our body becomes old or broken they have to be cleared away and destroyed so that new cells can be formed. Mitochondria play as very important role as it decides which cells is suppose to be removed and destroyed.

Mitochondria plays a very important role as in absorbs the calcium, irons, and store in until it is needed to out body. Mitochondria is also helpful to produce heat in our body it can use a tissue called brown fat which can be used to generate heat. Brown fat is found at its highest level in infants and it slowly reduces as one persons age increases. These are the reasons by why it is called “energy currency of the cell”.
