What are cristae in mitochondria?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Cristae are the folded inner membranes of mitochondria that extend into the interior space (matrix). These fold-like structures significantly increase the surface area available for chemical reactions, particularly for the enzymes and proteins involved in ATP production through oxidative phosphorylation. The presence of cristae enhances the mitochondrion's efficiency in energy production by providing more space for the electron transport chain components.
