Question

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.

Answer 1

Answer:

Option (C).

Explanation:

Oxidative phosphorylation may be defined as the process of the production of ATP molecule by the use of enzyme and transfer of electrons from one complex to the other complex.

The liver cells has five times large surface area of inner mitochondrial membrane than the outer membrane. This increases the surface area of the inner mitochondrial membrane that increase the rate of the oxidative phosphorylation. The complexes of the electron transport chain is located in the inner mitochondrial membrane.

Thus, the correct answer is option (C).

Answer 2

Answer:

The correct answer is option C.

Explanation:

The inner membrane of the mitochondria in liver cells is about five times of that the outer membrane as it helps the expanding the surface area of the inner membrane including cristae which is compartment like structure in the inner membrane.

The expand in the surface area in the inner membrane that helps in enhancing its ability to produce ATP than normal. It increases the surface area for oxidative phosphorylation.

Thus, the correct answer is option C.
