The figure shows an organelle typically found in eukaryotic cells. Which of the following best describes the function of the double membrane system of this organelle?

• The outer membrane allows the transport of all molecules into the intermembrane space, while the inner membrane serves as the regulatory boundary.

• The inner membrane has specialized proteins that create a hydrogen ion concentration gradient between the intermembrane space and the matrix.

• The outer membrane contains transport proteins that establish a sodium ion concentration gradient used for ATP production, while the inner membrane contains transport proteins that establish a hydrogen ion concentration gradient used for glucose production.

• The toxins and wastes entering a cell cross the outer membrane and are detoxified by digestive enzymes stored within the intermembrane space.
