Mitochondrial Energy Production Quiz

What is the primary role of NADH in the mitochondrion?

• To transport oxygen to the mitochondria

• To generate a proton gradient across the mitochondrial membrane

• To store energy for glycolysis

• To oxidize glucose directly

During the electron transport chain, where are electrons from NADH first transferred?

• Oxygen

• ATP synthase

• Coenzyme Q

• Cytochrome c

Which complex transfers electrons to oxygen, the terminal electron acceptor?

• Cytochrome bc1 complex

• NADH dehydrogenase

• Cytochrome c oxidase complex

• ATP synthase

What is the function of ATP synthase in the mitochondrion?

• To generate a proton gradient

• To synthesize ATP from ADP and phosphate

• To transfer electrons to oxygen

• To oxidize glucose

What is the process called when ATP is formed using the energy from a proton gradient?

• Glycolysis

• Oxidative phosphorylation

• Krebs cycle

• Electron transport
