In liver cells, the inner mitochondrial membranes are about five times the area of the outer mitochondrial membranes. What purpo
se 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.
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.
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.
The correct answer is D) integral membrane proteins.
Explanation:
257/5000
Ionic channels consist of oligomeric transmembrane integral proteins (formed by the assembly of several subunits). Said proteins act as gate channels that allow the passage of certain ions eg. calcium, sodium, potassium, etc.
When scientists try to use the explanation of the natural world to understand patterns, they are making PREDICTIONS about natural events. For example, volcanic eruptions.
