Respiration in Organisms — Science STD 7 — Question

The key to aerobic respiration lies within the mitochondria.
The mitochondrion is an organelle with a complex series of chemical reactions similar to the chloroplast.
The mitochondria, like the chloroplast, contains its own $DNA$, and it is has a double - membrane system.
The outer membrane is similar to any other organelle, but the inner membrane is folded, creating a lot of surface area.
The chemical reaction for aerobic respiration occurs on the surface of the inner mitochondrial membrane.
