The inner membrane of a mitochondrion has many folds.Why?
A) The folds protect the proteins in the inner membrane from the toxic by-products of cellular respiration.
B) The folds increase the space available for electron transport chains and ATP synthase molecules, increasing the efficiency of ATP production.
C) The extra folds make the mitochondrion more efficient at capturing carbon dioxide.
D) The antenna complexes in the inner membrane form clusters that force the membrane into folds.

Question

Quizplus · Accepted Answer

The folds in the inner membrane of a mitochondrion increase the surface area available for electron transport chains and ATP synthase molecules. This increases the efficiency of ATP production by allowing for more ATP to be synthesized per unit of space.
