The inner membrane of mitochondria throws itself into many folds. These folds are known as cristae. The cristae increase the available surface area to enhance the productivity of cellular respiration.
- Cristae are sub-compartments of the mitochondrial inner membrane, that folds into several shapes.
- These structures are found to increase the surface area available in order to boost cellular respiration productivity.
- Cristae are required for the proper functioning of mitochondria, that are labeled the cell’s powerhouse.
- Cristae junctions are cylindrical contacts between the folded cristae and the inner membrane.
- They also have protrusions that fold into the inner mitochondrial matrix and penetrate deep into it.
