The mitochondrial inner membrane form a series of infoldings known as cristae to:
a. increase surface area
b. decrease surface area
c. increase production of h+
d. decrease production of h+

Increase the surface area.

Explanation:

The mitochondria is an important cell organelle that is found in both the plant cell and animal cell.

It basically aids in the production of ATP, hence also known as the power house of the cell.

The mitochondria is a double membrane system in which the inner membrane of mitochondria helps in increasing the surface area for integral proteins.

It helps in embedding the proteins in the folding known as cristae.
