Nikhil Obrien · Answer 1

The correct answer is e. the passage of electrons from one energy-generating carrier to another

Explanation:

The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons pass from one member of the transport chain to the next in a series of redox reactions. The energy released in these reactions is captured as a proton gradient, which in turn is used to form ATP in a process called chemosmosis.

These transport molecules, in the inner mitochondrial membrane, are reduced and oxidized, accepting electrons and transferring them to the next molecule, electrons descending from high energy levels to lower ones, that is, from one energy-generating carrier to another. When lowering to other levels, energy is released that will be used in the synthesis of ATP by oxidative phosphorylation.
