Question

Why is the inner layer of mitochondria folded?

Answer 1

the inner layer of mitochondria folded because it increases surface area.

The inner membrane of the mitochondria is folded to make more surface area where chemical reactions can take place. The more the folds, the bigger the surface. These folds are called cristae.

Answer 2

hola mate.....here is your answer....

the inner membranal layer of mitochondria contains enymes required for ETS i.e. electron transport system.......it also contains oxysome particles , so to provide more content of enzymes and oxysomes , the mitochondria increases the size and length of its inner layer , to fix up this layer in comparitively small mitochondrial structure , it gets folded , these folds are cistae......

hope u understood ^_^
