8. The inner membrane of a mitochondrion is folded 8. The inner membrane of a mitochondrion is folded. These folds are called christae. How might cellular respiration be different if the inner mitochondrial membrane were not folded?

8. The inner membrane of a mitochondrion is folded 8. The inner membrane of a mitochondrion is folded. These folds are called christae. How might cellular respiration be different if the inner mitochondrial membrane were not folded? The christae increase the surface area of the inner wall of the mitochondria, which allows more electron transport chain pathways and ATP synthase. Thus the rate of cellular respiration is increased.
