Exposing inner mitochondrial membranes to ultrasonic vibrations will disrupt the membranes. However, the fragments will reseal "inside out." The little vesicles that result can still transfer electrons from NADH to oxygen and synthesize ATP. After the disruption, which components involved in oxidative phosphorylation must be present for electron transfer and ATP synthesis to still occur?
A) only the electron transport system
B) only the ATP synthase system
C) all of the electron transport system and the proteins that add CoA to acetyl groups
D) all of the electron transport system and ATP synthase

Question

Quizplus · Accepted Answer

Both the electron transport system and ATP synthase are necessary components of oxidative phosphorylation for electron transfer and ATP synthesis to occur. Therefore, all of the electron transport system and ATP synthase must be present for these processes to still occur after disrupting the inner mitochondrial membranes.
