The inner membranes of both mitochondria and chloroplasts are folded into various arrangements. What is the advantage of having a folded membrane rather than a simple interior membrane that follows the same oval shape as the exterior membrane?

The question is incomplete as itt does not have the options which are:

A) The folds in the membranes are a physical barrier for compounds that attempt to enter the organelle.

B) The folds allow for more surface area for the chemical reactions that occur across the inner membranes.

C) The folds allow these organelles to interact more efficiently with Golgi bodies.

D) The folds cause a necessary change in the organelles' internal pH.

B) The folds allow for more surface area for the chemical reactions that occur across the inner membranes.

Explanation:

The mitochondria and chloroplast are double-membrane organelle that contains the outer and inner layer.

The outer layer is usually smooth of both the chloroplast and mitochondria but the inner membrane is not regular but folded.

The folding is an adaptive feature of these organelle to increase the surface area. The increased surface area allows the more ATPase in the inner membrane, therefore, increases the amount of ATP generated.

Thus, Option-B is correct.

answer; i believe the correct answer is ( proteins );
