2.28 Electron Transport

Front

What do FADH2 and NADH bring to the electron transport chain?

Back

Electrons.

Front

What is a reactant for the electron transport chain?

Back

Oxygen.

Front

What process enables ATP synthase to function?

Back

Diffusion.

Front

What is created when protons are pumped outside the matrix across the inner membrane?

Back

A concentration gradient of H+ ions (protons).

Front

What does ATP synthase do?

Back

Creates ATP in chemiosmosis.

Front

What is the main function of the electron transport chain?

Back

To transfer electrons and create a proton gradient.

Front

What is the final electron acceptor in the electron transport chain?

Back

Oxygen.

Front

What is chemiosmosis?

Back

The movement of ions across a selectively permeable membrane, down their electrochemical gradient.

Front

What role do protons (H+) play in ATP production?

Back

They create a proton gradient that drives ATP synthesis.

Front

What is the significance of the proton gradient in the electron transport chain?

Back

It powers ATP synthase to produce ATP.
