A cross section of a mitochondrion showing the inner membrane folded into cristae.
Where in the mitochondrion is the electron transport chain located?
- Acheck_circle
Embedded in the inner membrane (cristae)
- B
Floating freely in the matrix
- C
On the outer membrane
- D
In the intermembrane space
Explanation
ETC complexes are integral proteins of the inner mitochondrial membrane. Cristae folding maximizes surface area and ETC capacity.
