Concept explainers
(a)
Interpretation:
The flux of nutrient molecules down a given concentration gradient has to be determined.
Concept introduction:
Simple diffusion: The moment of molecules move down the concentration gradient is known as simple diffusion.
Facilitated diffusion: The moment of molecules against the (move up) the concentration gradient and changes the shape of the membrane is known as facilitated diffusion.
Fermi diffusion law: The density of states tells us how many states exist at a given energy (E), The fermi function f(E) specified how many of the existing states at the energy E will be filled with electrons. The function f(E) specifies, under equilibrium conditions the probability that an available state at an energy (E) will be occupied by an electrons. It is a probability distribution function.
Fermi equation:
(b)
Interpretation:
The amount of molecules passing through the given area in the given time has to be calculated.
