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 synthesise 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.

Both the electron transport system and the ATP synthase system must be present for electron transfer and ATP synthesis to still occur. The disruption of inner mitochondrial membranes does not affect the proteins that add CoA to acetyl groups.
