Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The inner membrane of the mitochondrion has many folds called cristae. Which statement best explains the significance of this structure?
A
The folds increase the absorption of carbon dioxide
B
The folds increase the surface area for cellular respiration (breaking down glucose to release energy:ATP)
C
The folds increase the absorption of oxygen.
D
The folds increase the surface area for photosynthesis (absorbing sunlight to produce glucose)
Explanation: 

Detailed explanation-1: -To increase the capacity of the mitochondrion to synthesize ATP, the inner membrane is folded to form cristae. These folds allow a much greater amount of electron transport chain enzymes and ATP synthase to be packed into the mitochondrion.

Detailed explanation-2: -Mitochondrial cristae are the folds within the inner mitochondrial membrane. These folds allow for increased surface area in which chemical reactions, such as the redox reactions, can take place.

Detailed explanation-3: -Mitochondrial cristae are the folds of the inner mitochondrial membrane. These folds increase the surface area of the membrane and help make the mitochondrion more efficient.

Detailed explanation-4: -Mitochondria, organelles specialized to carry out aerobic respiration, contain an inner membrane folded into cristae, which form two separate compartments: the inner membrane space and the matrix.
