Which of the following statements about the mitochondrial inner membrane is TRUE?
(I) The inner membrane is permeable to CO₂,H₂O,and small ions.
(II) The inner membrane contains several transport proteins and membrane bound
Enzymes.
(III) In general,a higher inner membrane surface area correlates to a higher rate of
Respiration.
(IV) The number of cristae reflects the respiratory activity of the cell.

Question

Quizplus · Accepted Answer

The inner membrane is not freely permeable to ions or molecules like CO2 and H2O without specific transporters. It does contain transport proteins and enzymes crucial for cellular respiration, and both the surface area and the number of cristae are indeed related to the cell's respiratory activity.
