Read the given statements: Statement I: Mitochondrial inner membrane encloses the matrix. Statement II: The inner membrane forms infoldings called cristae. Choose the correct option:

Step-by-step solution

The mitochondrion is bound by a double membrane. The inner membrane encloses the matrix , so Statement I is correct. The inner membrane is also thrown into a number of infoldings called cristae towards the matrix, which increase the surface area for the enzymes of oxidative phosphorylation, so Statement II is also correct. Hence both statements are correct.
