Which organelle is known as the powerhouse of the cell? Why?

Answer : Mitochondria are known as the powerhousesof the cell. Because, the energy required for various chemical activities needed for life is released by mitochondria in the form of ATP(Adenosine triphopshate) molecules. ATP is known as the energy currency of the cell. The body uses energy stored in ATP for making new chemical compounds and for mechanical work. Mitochondria have two membrane coverings instead of just one. The outer membrane is very porous while the inner membrane is deeply folded. These folds create
a large surface area for ATP-generating chemical reactions. Mitochondria are strange organelles in the sense that they have their own DNA and ribosomes. Therefore, mitochondria are able to make some of their own proteins.
