ADVERTISEMENTS:
The upcoming discussion will update you about the differences between Outer and Inner Mitochondrial Membranes.
Difference # Outer Mitochondrial Membranes:
1. The membrane is smooth.
2. It bears porins or protein lined channels.
ADVERTISEMENTS:
ADVERTISEMENTS:
3. Enzymes are fewer.
4. Folding’s are absent.
5. Protein content is roughly equal to that of lipids.
6. Cholesterol and other lipids are present. Cardiolipins are absent.
ADVERTISEMENTS:
7. Electron transport system (ETS) is absent.
8. It is permeable to most biochemical.
Difference # Inner Mitochondrial Membranes:
1. It contains a number of particles.
2. It bears carrier and other transport proteins.
3. It contains a number of enzymes.
4. Inner mitochondrial membrane develops a large number of infolding’s called cristae.
5. Protein content is quite high (up to 80%) while lipid content is low.
6. Cardiolipins occur.
ADVERTISEMENTS:
7. ETS present in inner membrane.
8. It is selectively permeable.
