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.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
