Where is the location of ETC occur?
A
inner membrane of mitochondria including matrix
B
Inner membrane of mitochondria including outer membrane
C
Inner membrane of mitochondria including intermembrane space
D
Inner membrane of mitochondria including cristae
Explanation: 

Detailed explanation-1: –The electron transport system takes place in the cristae present in the inner membrane of the mitochondria. Cristae are the infoldings of the inner membrane of the mitochondria and it aids in the cellular respiration. It contains a number of cytochromes and enzyme ATP synthase.
