The correct sequences of electron acceptor in ATP synthesis is

Options

A. Cyt a a b c
B. Cyt b c a `a_(3)`
C. Cyt b c `a_(3)` a
D. Cyt c b a `a_(3)`

Answer

B

Explanation

These are arranged in order of their increasing redox potential and electron flow through the chain in step wise manner from the more electronegative compound to the more electropositive `O_(2)`. On the basis of redox potential cytochrome acceptor order is cyt b c a `d_(3)`.
