Consider a cell membrane at 298K which has glucose at the concentration of 200mM inside the cell and 20 mM outside the cell, wit
h the voltage being 50 mV lower in the interior. Calculate the molar free energy difference for transporting a glucose molecule from the exterior to the interior of the cell.A. -2.7 kJ/molB. -5.7 kJ/molC. +2.7 kJ/molD. +5.7 kJ/mol
Molar free energy (ΔG) in the transportation of uncharged molecules as glucse through a cell membrane from the exterior to the interior of the cell is defined as:
ΔG = RT ln C in / C out
knowing R is 8,314472 kJ/molK; T is 298K Cin = 200mM and Cout = 20mM
The outer core is the only layer that is liquid. It is also mainly made from nickel and iron. The main job of the outer core is that it's responsible for the Earth's magnetic field. As the earth spins, the liquid inside this layer spins aswell, keeping it balanced.
