Which of the following statements regarding mitochondria is incorrect?
Options
- AOuter membrane is permeable to monomers of carbohydrates, fats and proteins.
- BEnzymes of electron transport are embedded in outer membrane.
- CInner membrane is convoluted with infoldings.
- DMitochondria matrix contains single circular DNA molecule and ribosomes.
Correct answer
B. Enzymes of electron transport are embedded in outer membrane.
Step-by-step solution
The thickness of the outer mitochondrial membrane, which encloses the entire organelle, is 60 to 75 angstroms Å . It has a protein-to-phospholipid ratio similar to that of the cell membrane (about 1:1 by weight). It consists of a large number of porins, an integral membrane proteins. The pore-forming voltage-dependent anion channel is the major trafficking protein. The inner membrane of mitochondria has convoluted foldings. The inner membrane encloses the matrix. It consists of 2/3 of the total protein in a mitocho
