Question

The third stage of cellular respiration is (2 points)

Answer 1

The election transport chain

Answer 2

Electron Transport Chain

In the third stage, electrons from the NADH and FADH2 molecules move to the electron transport chain (ETC). These electrons generate the required power to move protons through the mitochondria into the space between membranes. In the final stage of cellular respiration, oxygen combines with the electrons and protons to form water.
