Electron Transport Chain exam Flashcards

A series of protein complexes located in the inner mitochondrial membrane that transfer electrons from NADH and FADH2 to oxygen, creating a proton gradient.

In the inner mitochondrial membrane.

Electron carriers that donate electrons to the electron transport chain.

Oxygen (O2).

Oxidation-reduction reactions where electrons are transferred between molecules.

Water (H2O).

The space between the inner and outer mitochondrial membranes where protons are pumped to create a gradient.

To drive ATP synthesis via oxidative phosphorylation.

The process of generating ATP using the energy derived from the electron transport chain and the proton gradient.

They are oxidized to NAD+ and FAD, respectively.

The innermost compartment of the mitochondria, enclosed by the inner membrane.

It houses the protein complexes and is the site where the proton gradient is established.

The movement of ions across a semipermeable membrane, down their electrochemical gradient, which in mitochondria is used to generate ATP.

It uses the proton gradient to synthesize ATP from ADP and inorganic phosphate.

A process of cellular respiration that requires oxygen to produce ATP.

ATP, water, and oxidized electron carriers (NAD+ and FAD).

A difference in proton concentration across the inner mitochondrial membrane, essential for ATP production.

It acts as the final electron acceptor, forming water.

To transfer electrons from NADH and FADH2 to oxygen, creating a proton gradient that drives ATP synthesis.

The membrane where the electron transport chain is located and where the proton gradient is established.

The ETC creates a proton gradient that is used by chemiosmosis to produce ATP.

Adenosine triphosphate, the primary energy carrier in cells.

They undergo a series of redox reactions, releasing energy used to pump protons into the intermembrane space.

A gradient formed by the accumulation of protons in the intermembrane space, driving ATP synthesis.

They donate electrons to the ETC, which are used to create a proton gradient for ATP production.

A byproduct of the electron transport chain when oxygen accepts electrons and combines with protons.

It is where protons are pumped to create a high concentration gradient necessary for ATP synthesis.
