Question

The outer membrane is smooth and forms the continuous limiting boundary of the mitochondria. Explain​

Answer 1

Answer:

The outer membrane is the gateway to the mitochondrion, just like the cell membrane is for the cell.

It has porins to allow smaller proteins in and protein complexes to allow bigger proteins in.

It works in concert with the inner membrane to allow these proteins into the matrix.

The outer membrane is smooth and forms the continuous limiting boundary of the mitochondria whereas the inner membrane forms a number of infoldings called the cristae.

Due to the presence of two membranes, the organelle is partitioned into two distinct chambers filled with aqueous fluid.

We all read a famous phrase in the mitochondrial part of the Cell biology, "The Outer membrane is smooth and Inner membrane bears Cristae and surrounds the matrix." Mostly, we read about the inner membrane because there is a lot to know about the reactions and processes that takes place in the inner membrane, but there are several importances of the Outer membrane also.

✤ OUTER MEMBRANE:

• The Outer membrane is smooth but contains some pores where it works along with inner membrane to let some substances in.
• Basically it surrounds the main respiratory area of an eukaryotic cell, because the mitochondria is the power house of the cell and meant for Cellular respiration.

Let's know more about the cell organelle 'Mitocondria':

• They are double membrane bound organellesfound in Eukaryotic cells.
• Hence, they are known as prokaryotes wrapped in cell's own membrane.
• The Outer membrane is smooth.
• The inner membrane bears Cristae which increases the surface area of cellular processes.
• Cristae consists of Elementary particles or F0/F1 particles or Oxysomes.
• They help in oxidation of food and cellular respiration.
• Thus, they are known as Power house of the cell.
• They are semi-autonomous bodies and have their own DNA and ribosomes.
