What do cristae do in mitochondria?

Answer by  MikeyH (6)

Cristae are chambers formed within the inner membrane of mitochondria. They contain proteins and various membrane-bound hemoproteins. They increase the area in which chemical reactions can occur within the mitochondria. This enables oxidative metabolism to take place.
