These are folds in the mitochondria that contain enzymes important to atp production and also increase the surface area for atp production.

The correct answer will be-true

Explanation:

Mitochondria is a double membrane-bound organelle which is involved in the production of the energy molecules called ATP.

For the production and increase the productivity of the ATP molecules, the cell has modified the mitochondria by making the changes in the inner surface of the organelle.

The inner membrane possesses the enzyme called ATP synthase which synthesizes the enzymes. The inner membrane increases the infoldings called cristae which increases the surface area for the ATP production.

Thus, true is the correct answer.
