Expert Answer:

Mitochondria are membrane-bound organelles having a double membrane. The outer membrane is fairly smooth. But the inner membrane is highly convoluted, forming folds called cristae. Cristae are the internal compartments formed by the inner membrane of a mitochondrion. They are studded with proteins, including ATP synthase and a variety of cytochromes.
The cristae greatly increase the inner membrane's surface area. It is on these cristae that food (sugar) is combined with oxygen to produce ATP - the primary energy source for the cell. Cristae are a necessity for the mitochondria to function efficiently.
