The Functioning of an Electron Transport Chain Is Analogous to

question 25

Multiple Choice

The functioning of an electron transport chain is analogous to

• A) playing tennis.
• B) a rock falling from a cliff.
• C) a person jumping from the top to the bottom of a flight of stairs in one jump.
• D) a person descending a flight of stairs one step at a time.
• E) a person jumping rope. High-energy electrons enter the electron transport chain by way of NADH and FADH₂. Energy is captured through a series of reactions that release a small amount of energy each time. During these oxidation-reduction reactions, each of the carriers become reduced and then oxidized as electrons move down the system. As the pair of electrons is passed from carrier to carrier, energy is released in small amounts and captured for ATP production.
