Mitochondrion
Make it clearer
A mitochondrion is an organelle, a specialized structure inside a cell. Its central job is to convert energy from food into a form the cell can use.
Think of it as an energy-conversion station. Through oxidative phosphorylation, the mitochondrion produces ATP, a major source of cellular energy. It also carries a small amount of its own DNA, separate from most of the cell's DNA in the nucleus.
In brief
A mitochondrion is a cellular organelle that converts energy from food into a form the cell can use.
Through oxidative phosphorylation, it produces ATP, a major source of cellular energy. It also contains a small amount of its own DNA.
Think of a station inside the cell that converts chemical energy from food into ATP, the usable energy form the cell relies on.
