Vedclass · Answer

(A) In the electron transport system $(ETS)$ of mitochondria, the transfer of electrons between specific complexes is coupled with the pumping of protons $(H^+)$ from the matrix to the intermembrane space. Specifically, the transfer of electrons from $Cyt$ $b$ to $Cyt$ $c_1$ (part of Complex $III$) is associated with the translocation of protons across the inner mitochondrial membrane. This proton gradient creates a proton motive force that drives the synthesis of $ATP$ via $ATP$ synthase ($Complex$ $V$). Therefore, the passage of electrons from $Cyt$ $b$ to $Cyt$ $c_1$ is a critical step in the energy-coupling process that leads to $ATP$ formation.
