Final answer:

Electrons are transported to the membrane at the beginning of the electron transport chain process by two electron carriers NADH and FADH2.


Explanation:

Electrons are transported to the membrane at the beginning of the electron transport chain process by two electron carriers NADH and FADH2. These carriers pass electrons to the electron transport chain embedded in the inner mitochondrial membrane. The energy from these electrons is used to pump protons across the membrane, creating a transmembrane electrochemical gradient.
