oxidative phosphorylation

In a cell's energy factory, where does the process of oxidative phosphorylation take place within the mitochondria?

• Outer mitochondrial membrane

• Inner mitochondrial membrane

In a cellular energy factory, what are the two main components that work together to produce ATP through oxidative phosphorylation?

• NADH and FADH2

• Electron transport chain and chemiosmosis

In the process of oxidative phosphorylation, which molecule donates electrons to Complex I of the electron transport chain?

• FADH2

• NADH

In the process of oxidative phosphorylation, which coenzyme donates electrons to Complex II during cellular respiration?

• FADH2

• Coenzyme A

• NADH

In the process of oxidative phosphorylation, what is the final electron acceptor in the electron transport chain?

• NADH

• FADH2

• Oxygen

What is formed when oxygen accepts electrons and protons during oxidative phosphorylation at the

end of the electron transport chain?

• Hydrogen gas (H2)

• Water (H2O)

• Carbon dioxide (CO2)

How does oxidative phosphorylation create a proton gradient?

• The oxidative phosphorylation generates ATP directly without a proton gradient.

• Protons are released into the mitochondrial matrix during oxidative phosphorylation.

• By pumping H+ ions from mitochondrial matrix into the intermembrane space

Which enzyme is responsible for ATP synthesis during oxidative phosphorylation?

• ATP synthase

• Creatine kinase

• ATPase

What is the process called where photons move back into the

mitochondrial matrix through ATP synthase during oxidative phosphorylation?

• Chemiosmosis

• Oxidative phosphorylation

• Photophosphorylation

In the process of cellular respiration, how many ATP molecules are produced from one NADH

during oxidative phosphorylation?

• 2.5

• 1.5

• 3.0
