Terminal cytochrome of respiratory chain...

Terminal cytochrome of respiratory chain which donates electrons to oxygen is

A

cyt-b

B

cyt-c

C

`cyt-a_(1)`

D

`cyt-a_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
The ETS system contains various electron carriers such as cytochromes. The correct sequence of electron carrier/acceptor in ATP synthesis is cyt-b, cyt-`c_(1)`, cyt-c, cyt (a and cyt-`a_(3)`). Cyt-`a_(3)` is the terminal cytochrome, it possess two copper centers, which help in transfer of electron to oxygen.
