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.

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.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
