The inner membrane of mitochondria form extensive infoldings called _.
Correct answer: A. Cristae
- A. Cristae
- B. Cisternae
- C. Lamella
- D. Bifida
Explanation
The inner membrane of mitochondria is highly specialized and forms numerous infoldings known as cristae. These structures are vital as they increase the surface area of the membrane, allowing for more space for the electron transport chain and ATP synthase, which are key components in the production of ATP. The other options are incorrect: cisternae are associated with the endoplasmic reticulum and Golgi apparatus, lamella refers to a general thin layer or membrane, and bifida pertains to a medical condition unrelated to cell structure.
