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

Question

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

Answer 1

The correct answer is:

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

Mitochondria have a highly folded inner membrane, which forms structures known as cristae. This increased surface area allows for a greater number of sites for biochemical reactions, particularly those involved in ATP production during cellular respiration. This structural feature is crucial for the mitochondrion's function as the powerhouse of the cell, where energy production occurs.
