Question
Answer:
- Mitochondria are membrane-bound organelles present in the cytoplasm of all eukaryotic cells, that produces adinosine triphosphate (ATP), the main energy molecule used by the cell.
- Mitochondria known as the “Powerhouse of the cell,”.
- mitochondria are a double membrane-bound organelle found in most eukaryotic organisms.
- They are found inside the cytoplasm and essentially functions as the cell’s “digestive system.”
Structure of Mitochondria:
- The mitochondrion is a double-membraned, rod-shaped structure found in both plant and animal cell.
- Its size ranges from 0.5 to 1.0 micrometre in diameter.
- The structure comprises an outer membrane, an inner membrane, and a gel-like material called the matrix.
- The outer membrane and the inner membrane are made of proteins and phospholipid layers separated by the intermembrane space.
- The outer membrane covers the surface of the mitochondrion and has a large number of special proteins known as porins.
- It is freely permeable to ions, nutrient molecules, energy molecules like the ADP and ATP molecules.

Answer:
A mithochondria is a double membrane-bound organelle found in most eykaryotic organisms .Mithochondria generate most of the cells supply of adenosine triphosphrate,used as a source of chemical energy .Mithochondria were first discovered by Kolliker in the voluntary muscles of insects.
