Answer:
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
- 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.
