Question

Both the membranes of mitochondrion are

• A. structurally different but functionally similar.
• B. structurally as well as functionally different.
• C. structurally similar but functionally different.
• D. structurally different but functionally similar.

Answer 1

The correct option is B structurally as well as functionally different.

The mitochondrion is a double membrane-bound organelle found in most eukaryotic cells. It contains an outer and an inner membrane composed of phospholipid bilayers and proteins. The outer membrane covers the organelle while the inner membrane have several folds forming a structure called cristae.
