The inner mitochondrial membrane is selectively permeable and highly impermeable to ions and polar molecules due to the presence of transport proteins like ATP synthase and carriers for metabolites. This allows for the establishment of a proton gradient necessary for ATP production. In contrast, the outer mitochondrial membrane is more permeable and allows for the passage of ions, metabolites, and small proteins, facilitating communication and transport of molecules between the mitochondria and the cytosol.
What else can I help you with?
What are mitochondria surrounded by?
Mitochondria are surrounded by membranes.They have two membranes.
What are the ribbonlike folds on the inner lining of the mitochondrial membrane call?
The ribbon-like folds on the inner lining of the mitochondrial membrane are called cristae.
Structure of a mitochondria?
A mitochondrion contains outer and inner membranes composed of phospholipid bilayers and proteins. The two membranes, however, have different properties. Because of this double-membraned organization, there are five distinct compartments within the mitochondrion. There is the outer mitochondrial membrane, the intermembrane space (the space between the outer and inner membranes), the inner mitochondrial membrane, the cristae space (formed by infoldings of the inner membrane), and the matrix (space within the inner membrane).
What process of cellular respiration would be interrupted if the inner mitochondrial membranes were damaged?
The process that would be interrupted is the Electron Transport Chain. This is because the inner mitochondrial membrane is where the proteins and complexes needed for electron transport are located. Damage to this membrane would disrupt the flow of electrons and the production of ATP, which is the final step in cellular respiration.
What determines whether or not a substance can be actively transported through the membrane?
Active transport can only occur at intact, closed membranes. Such membranes can envelop very different compartments, like the whole cell, vesicles, the vacuole, the mitochondrial matrix, the inner thylacoid space of the chloroplasts, etc.
What is the space inside the folds of the inner mitochondrial membranes?
The space on the very inside of the mitochondria past the cristae (folds in the inner membrane) is called the mitochondrial matrix.
What is the purpose of the inner mitochondrial membranes being five times the area of the outer mitochondrial membranes and 17 times that of the cells plasma membrane?
It increases the surface for oxidative phosphorylation

Why aren't protons able to diffuse through the inner mitochondrial membrane?
Protons are unable to diffuse through the inner mitochondrial membrane because the membrane contains proteins called ATP synthase that provide a specific pathway for protons to pass through. This selective permeability allows protons to be utilized by ATP synthase to generate ATP during oxidative phosphorylation.
