Vedclass · Answer

(A) The correct sequence of cytochromes in the electron transport chain $(ETC)$ of the inner mitochondrial membrane is $cyt$ $b \rightarrow cyt$ $c_1 \rightarrow cyt$ $c \rightarrow cyt$ $a \rightarrow cyt$ $a_3$. Electrons are transferred from $cyt$ $b$ to $cyt$ $c_1$,then to $cyt$ $c$,and finally to the $cyt$ $a$-$a_3$ complex,which transfers them to oxygen. Therefore,the correct order is $cyt$ $b$,$cyt$ $c$,$cyt$ $a$-$cyt$ $a_3$.
