Electron Transport Chain Flashcard

Front

What is the primary function of the electron transport chain in cellular respiration?

Back

To generate ATP through oxidative phosphorylation

Front

During the electron transport chain, which molecule serves as the final electron acceptor?

Back

Oxygen

Front

How does the electron transport chain contribute to the proton gradient across the inner mitochondrial membrane?

Back

By using energy released from electron transfers to pump protons into the intermembrane space

Front

How do high-energy electrons from glycolysis and the Krebs cycle contribute to the formation of ATP from ADP in the electron transport chain?

Back

High-energy electrons pass through the electron transport chain to supply the needed energy to synthesize ATP from ADP.

Front

What is the main role of NADH and FADH₂ in the electron transport chain?

Back

They donate electrons.

Front

What does the movement of electrons through the electron transport chain create?

Back

A proton gradient.

Front

What role do the electrons play in the electron transport chain, and what is the ultimate fate of these electrons?

Back

They are transferred to oxygen, forming water.
