Question

The mitochondrial inner membrane consists of a number of infoldings called cristae. The increased surface area due to cristae helps in:

• A. Increasing the volume of mitochondria
• B. Incorporating more of the protein complexes essential for electron transport chain
• C. Changing the pH
• D. Increasing diffusion of ions.

Answer 1

The correct option is B

Incorporating more of the protein complexes essential for electron transport chain

Cristae provides more surface area for oxidative phosphorylation (ETS)
