Question

The cristae of mitochondria contain?

• A. Protein complex
• B. Lipid complexes
• C. Carbohydrate complexes
• D. All of these

Answer 1

The correct option is A Protein complex

Cristae are wrinkled to create more surface area inside the small mitochondria. Cristae are located on the inner membrane of mitochondria and mitochondria are located in the cell cytoplasm, not the nucleus.

The cristae define the third mitochondrial compartment, the crista lumen. The crista membranes contain most, if not all, of the fully assembled complexes of the electron transport chain and the ATP synthase.
