Vedclass · Answer

(A) The electron transport chain $(ETC)$ occurs in the inner mitochondrial membrane and consists of various electron carriers such as flavins,ubiquinone,and cytochromes.In aerobic respiration,electrons are passed through these carriers to the final electron acceptor.The sequence of electron transport is:$NADH + H^+ \rightarrow FMN \rightarrow Co-Q \rightarrow Cyt-b \rightarrow Cyt-c_1 \rightarrow Cyt-c \rightarrow Cyt-a \rightarrow Cyt-a_3 \rightarrow O_2$.Oxygen $(O_2)$ acts as the final electron acceptor,where it combines with electrons and protons to form water $(H_2O)$.
