Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Describe what would happen if the mitochondrial inner membrane was ruptured.
A
ATP synthesis would be inhibited
B
ATP synthesis would be promoted
C
The electron transport chain would increase in activity
D
The electron transport chain would decrease in activity
Explanation: 

Detailed explanation-1: -Inhibition of the ATP synthase compromises the output of ATP by OXPHOS and rewires energy metabolism to an enhanced glycolysis.

Detailed explanation-2: -Widespread damage to mitochondria causes cells to die because they can no longer produce enough energy. Indeed, mitochondria themselves unleash the enzymes responsible for cell death.

Detailed explanation-3: -If your mitochondria are not working properly then you are less able to convert food into ATP. For cells that require a lot of ATP, for example your muscles, this is a problem and they may become weaker and get tired faster.

Detailed explanation-4: -The inner membrane of the mitochondrion contains the components of the electron transport chain. Oxidation/reduction reactions along the components of the electron transport chain generate a proton gradient that is used by ATP synthase to phosphorylate ADP, thereby producing ATP.
