Which of the following statements regarding mitochondrial membrane is not correct?
- The outer membrane is permeable to all kinds of molecules
- The enzymes of the electron transfer chain are embedded in the outer membrane
- The inner membrane is highly convoluted forming a series of infoldings
- The outer membrane resembles a sieve
The Correct Option is B
Solution and Explanation
In mitochondria, the enzymes of the electron transport chain (ETC) are not embedded in the outer membrane but rather in the inner mitochondrial membrane. The inner mitochondrial membrane is where the ETC proteins and complexes are located, and it plays a crucial role in oxidative phosphorylation and ATP production. The outer membrane of mitochondria is relatively permeable and contains porins, which allow the passage of various molecules, but it does not contain the ETC enzymes.
So, the correct option is (B): The enzymes of the electron transfer chain are embedded in the outer membrane

Concepts Used:
Eurkaryotic Cells - Golgi Apparatus
The Golgi apparatus is also known as the Golgi complex or the Golgi body. The term is derived from Camillo Golgi, the scientist who discovered the organelle. It can be found in all eukaryotic cells, including plants and animals. They are membrane-bound organelles found in the cell's cytoplasm.
Formation of acrosome: The acrosome is a component of the tip of animal sperms that aids in the digestion of the egg or ovum covering sheath during fertilisation. The Golgi complex produces it with the help of its vesicles.
