Question

Electron transport chain occurs on:

• A. Outer membrane of mitochondria
• B. Inner membrane of mitochondria
• C. Matrix of mitochondria
• D. None of the above

Answer 1

The correct option is B Inner membrane of mitochondria

Electron transport system- This process takes place in cristae of mitochondria. Here are enzyme and coenzymes are present. These two carry and transfer electrons. During glycolysis electron carriers are reduced. Then electrons protons are donated by carries to electron carrier proteins.

It is finally accepted by oxygen. Now, they all together form water molecules.

(B) Inner membrane of mitochondria enzymes are present theme.
