How is a mitochondrion's structure related to its function?

Question

a
The complex folding pattern of the mitochondrion's membrane provides many sites where reactions can occur.
b
Mitochondria have no internal membranes.
c
The complex folding pattern of the mitochondrion's membrane does not provide many sites where reactions can occur.
d
The mitochondrion's internal membrane is not folded, which allows more sites for reactions.

Answer 1

The correct answer is:

a. The complex folding pattern of the mitochondrion's membrane provides many sites where reactions can occur.

This is because the inner membrane of the mitochondrion is highly folded into structures called cristae, which increases its surface area. This structure is crucial for its function in cellular respiration, as it allows for a greater number of protein complexes and enzymes to be embedded in the membrane, facilitating the processes of ATP production through oxidative phosphorylation.
