Exposing Inner Mitochondrial Membranes to Ultrasonic Vibrations Will Disrupt the Membranes

question 56

Multiple Choice

Exposing inner mitochondrial membranes to ultrasonic vibrations will disrupt the membranes. However, the fragments will reseal "inside out." These little vesicles that result can still transfer electrons from NADH to oxygen and synthesize ATP. If the membranes are agitated further, however, the ability to synthesize ATP is lost.
-After the first disruption, when electron transfer and ATP synthesis still occur, what must be present?

• A) all of the electron transport proteins as well as ATP synthase
• B) all of the electron transport system and the ability to add CoA to acetyl groups
• C) the ATP synthase system
• D) the electron transport system
• E) plasma membranes like those bacteria use for respiration
