Question

The observations that strongly support the view that mitochondria contain ETS enzymes aggregated into compact association is

• A. A contractile protein capable of utilizing ATP has been obtained from mitochondria.
• B. Mitochondria have a highly folder inner wall.
• C. Disruption of mitochondria yields membrane fragments which are able to synthesize ATP.
• D. All of the above.

Answer 1

The correct option is C Disruption of mitochondria yields membrane fragments which are able to synthesize ATP.

Mitochondria is a double membrane bound cell organelle. The outer smooth membrane and the inner membrane is in folded into cristae. The cristae contain the platform for the electron transport chain and ATP synthesis. If the outer mitochondrial membrane is removed and inner membrane is disrupted, it results in minute vesicles carrying electron carriers and coated with F${}_0$F${}_1$ particles which can carry out ATP synthesis as long as a proton gradient exists on two sides of the membrane also get disrupt. Thus, the correct answer is option C.
