Question

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, when electron transfer and ATP synthesis still occur, what must be present?

A) all of the electron transport proteins and 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

Answer 1

Answer: option D - the electron transport system

Explanation:

The electron transport system BASICALLY involves the transfer ofelectrons from NADH to oxygen coupled with the synthesis of ATP.

Note that electron transport system occurs in the INNER Mitochondrial membranes.
