Question

what is mitochondria​

Answer 1

Explanation:

Mitochondria (sing. mitochondrion) are organelles, or parts of a eukaryote cell. They are in the cytoplasm, not the nucleus. They make most of the cell's supply of adenosine triphosphate (ATP), a molecule that cells use as a source of energy. ... They oxidise glucose to provide energy for the cell.

Answer 2

A mitochondrion is a double membrane-bound organelle found in most eukaryotic organisms. Mitochondria generate most of the cell's supply of adenosine triphosphate, used as a source of chemical energy. Mitochondria were first discovered by Kolliker in the voluntary muscles of insects.
