Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
True or False:The inner walls are folded inward
A
True
B
False
Explanation: 

Detailed explanation-1: -The inner membrane of the mitochondrion folds inwards, forming the cristae. This folding allows a greater amount of membrane to be packed into the mitochondrion.

Detailed explanation-2: -The inner membrane (IM) has many folds, termed cristae, which increase the surface area available for mitochondrial respiration and are the site of electron transport and oxidative phosphorylation (OXPHOS).

Detailed explanation-3: -Mitochondria are double membraned with wall folded to form .

Detailed explanation-4: -Mitochondria are surrounded by a double-membrane system, consisting of inner and outer mitochondrial membranes separated by an intermembrane space (Figure 10.1). The inner membrane forms numerous folds (cristae), which extend into the interior (or matrix) of the organelle.
