In liver cells, the inner mitochondrial membranes are about five times the area of the outer mitochondrial membranes. What purpose must this serve?
A) It allows for an increased rate of glycolysis.
B) It allows for an increased rate of the citric acid cycle.
C) It increases the surface for oxidative phosphorylation.
D) It increases the surface for substrate-level phosphorylation.
E) It allows the liver cell to have more peroxisomes.

Question

The increased surface area of the inner mitochondrial membranes allows for more space for the proteins involved in oxidative phosphorylation. This increases the efficiency of ATP production, which is especially important for liver cells that have high energy demands.
