Verified step by step guidance

Understand the structure of mitochondria: Mitochondria are double-membraned organelles with an inner membrane that folds into structures called cristae. These folds are crucial for their function.

Recall the primary function of mitochondria: Mitochondria are known as the 'powerhouses' of the cell because they produce ATP (adenosine triphosphate), the main energy currency of the cell, through a process called oxidative phosphorylation.

Relate the structure of cristae to their function: The cristae increase the surface area of the inner mitochondrial membrane, which is where the electron transport chain and ATP synthase are located. This increased surface area allows for more space for these processes to occur, enhancing ATP production.

Eliminate incorrect options: (1) Cristae do not transport proteins out of the mitochondria; this is not their function. (2) Cristae do not synthesize ribosomes; ribosomes are synthesized in the nucleolus. (3) Cristae do not store genetic material; mitochondrial DNA is located in the matrix, not in the cristae.

Conclude the correct answer: The main function of cristae is to increase the surface area for ATP production, which aligns with the role of mitochondria in energy generation.
