Answer:
Change in free energy (ΔG) = 1.43 kcal/mol
Explanation:
Free energy is the energy released by a diffusing molecule moving up or down a concentration gradient, across a membrane.
The formula for free energy change import into a membrane is given by the formula :
![\triangle G = \triangle G^0 + R \times T \times In\frac{[X]_{inside}}{[X]_{outsdie}}](https://tex.z-dn.net/?f=%5Ctriangle%20G%20%3D%20%5Ctriangle%20G%5E0%20%2B%20R%20%5Ctimes%20T%20%5Ctimes%20In%5Cfrac%7B%5BX%5D_%7Binside%7D%7D%7B%5BX%5D_%7Boutsdie%7D%7D)
where:

![[X]_{inside} = concentration\ of\ glucose\ inside\ the\ cell = 0.5mM\\ {[X]}_{outside} = concentration\ of\ glucose\ outside\ the\ cell = 5mM](https://tex.z-dn.net/?f=%5BX%5D_%7Binside%7D%20%3D%20concentration%5C%20of%5C%20glucose%5C%20inside%5C%20the%5C%20cell%20%3D%200.5mM%5C%5C%20%7B%5BX%5D%7D_%7Boutside%7D%20%3D%20concentration%5C%20of%5C%20glucose%5C%20outside%5C%20the%5C%20cell%20%3D%205mM)
![\triangle G = 0 + (2) \times (310) \times In\frac{[0.5]}{[5]} \\\triangle G = 620 \times In (0.1)\\\triangle G = 620 \times (-2.3)\\\triangle G = -1426\ cal/mol\\\triangle G = 1.43\ kcal/mol](https://tex.z-dn.net/?f=%5Ctriangle%20G%20%3D%200%20%2B%20%282%29%20%5Ctimes%20%28310%29%20%5Ctimes%20In%5Cfrac%7B%5B0.5%5D%7D%7B%5B5%5D%7D%20%5C%5C%5Ctriangle%20G%20%3D%20620%20%5Ctimes%20In%20%280.1%29%5C%5C%5Ctriangle%20G%20%3D%20620%20%5Ctimes%20%28-2.3%29%5C%5C%5Ctriangle%20G%20%3D%20-1426%5C%20cal%2Fmol%5C%5C%5Ctriangle%20G%20%3D%201.43%5C%20kcal%2Fmol)
