Electron Transport Chain Quiz

The electron transport chain is often referred to as the main event of cellular respiration.

The electron transport chain is located in the inner membrane of the mitochondrion.

NADH delivers its electrons to the first protein in the electron transport chain.

<p>The final destination of the electrons is oxygen, which accepts the electrons and hydrogens to form water.</p> Signup and view all the answers
